I study biology, yet it have always seen to me, that cellular respiration processes are boring. Not so long ago I forced myself to learn about these processes, because of biology exams, so I watched Khan Academy videos about glycolisis, Krebs cycle and ETC and holy shit, my jaw was literally dropped. These processes are amazing.
This process takes place in the Mitochondria. The Mitochondria use to be its own individual cell because it produces ATP and has its own DNA structure.
Why do they have depressing music at the beginning? Shouldn't they be trying to coerce people into watching it? Although, I did see this one video of the sliding filament model that was basically a rave, hahaha. That made it confusing...
Excellent. Sure, it doesn't show everything involved in the chain (lactate dehydrogenase and so on), however it's perfect to understand the general process. Helped me a lot!
Nice animation, but the stoichiometries are not right.
NADH dehydrogenase pumps 4 protons per NADH
cytochrome b-c1 pumps 4 protons per ubiquinone (using the Q-cycle)
and cytochromo oxidase pumps 2 protons per 2 electrons.
So for each NADH oxidized you will pump 10 protons to the other side of the membrane. I found this info in my biochemistry book LEHNINGER, principles of biochemistry, used in al bachelor studies that have something to do with biochemistry.
WHOOP mf's found another complex- so complex 2 is succinate dehydrogenase and ATP synthase is now complex 5 which is NOT considered part of electron transport chain anymore as it only uses proton gradients to synth. ATP...
Yea have to agree. there are some faults in this video. Skipping complex II (FAD DH) and missing protons as mentioned, 4 protons for NADH DH, 4 protons for Cyt b-c1 and 2 protons for Cyt Ox.
Furthermore it takes 12protons to make 3 ATP, which means that that is an error too. (equivalent to 4 protons/ATP)

The video is wrong about net number of protons pumped across:
for NADH: 2 electrons go through chain pumping out 4 H+'s in complex I, 4 H+'s in III, and it's right for complex IV saying 2 H's for every electron pair.
for FADH: same but skips complex I and enters at II, pumping across 6 H's per el. pr.

It actually loses two electrons and a proton. The electron and proton are a hydrogen atom (hence, the 'H'). The loss of the second electron raises the oxidation number to +1.

The article says, “Red jasper cored from layers 3.46 B years old suggests that not only did the oceans contain ABUNDANT OXYGEN then, but that the atmosphere was AS OXYGEN RICH AS IT IS TODAY...”
So how did the amino acids link together with so much oxygen?
Also, how did so much oxygen get into the atmosphere from the time earth formed and cooled?
I appreciate the offer but prefer to keep these conversations public so everyone can see the arguments being presented by both sides.
And yes, I realize YT's 500 character format is cumbersome for these types of discussions. So just start with the highlights of your rebuttal and we can go from there.
@AA32m7io1I was strongly religous and I know a great deal of the bible, so i am not a typical one-sided i hate god type, i am extremely open minded, but I will turn towards logic and proof before I believe in other humans, because believe it or not people lie, even during biblical times. If you believe in miracles thats fine, but theres always a scientific cellular/chemical explanation, and have you ever thought that the stories in the bible are just overexaggerated to make a good story.
@AA32m7io1 possibly those rocks could have been placed at a totally different location then, then swept deep under, but still retaining their oxygen. But oxygen from where...shit. But just because we don't know something doesn't give us the right to give God the credit. We used to think god made the sun come up and down. I could write pages on this subject so I'll stop here and tell me what you have to say about it.
@AA32m7io1 Our atmosphere was not always rich in oxygen, sir. It was composed of Hydrogen and Helium. Note first oxygen appeared in oceans and atmospheres 2500 MYA.alright, I just read that article, and I admit, that is EXTREMELY interesting, i'm bringing that in tomorrow...wow. This is just me speaking here, thinking of explanation, the plates obviously have shifted a great deal and
@AA32m7io1 Nitrogen fixaters change N2 to NH3. CO2, N2, and water is all that cyanobacteria require. I have no clue what you are talking about with oxygen. . And your deep sea rock theory is also backed up with information and theories like all our oxygen and water got here from asteroids colliding with earth that were rich in those compounds. lol fail.
@AA32m7io1 120 period time frame, now you can't say that all of this information collaborated together is 100% accurate. Now I respect all religions and have nothing against god (God) but frankly, It just isn't logical.Now, I would like you to view a video of mine..."Christopher Hitchens - Christianity is Immoral". Now what you said," How did amino acids link together with somuch oxygen" WTF man??Nitrogen is essential for the production of amino acids and nucleic acids in organisms.
@AA32m7io1 "brainwash" their congregation, being that they bring them and tell 5 year old kids their ideals. And it goes from there, with that person obviously believing what he has been brought up to believe. My truth is not in "unrighteousness" but in facts. I am not trying to minimize god, just explain. The bible leaves no room for explanation. Will I go to hell because I believe in facts and not what the Bible says? The Bible was written by dozens of people within about a
“Now I respect all religions and have nothing against god (God) but frankly, It just isn't logical.”
Speaking of logic, where do the Laws of Logic come from? Since they are not physical in nature, what empirical evidence do you have that proves their existence?
Also, where do the Laws of Logic fit into Herbert Spencer's five categories of time, space, matter, force and action?
@AA32m7io1 Hey sorry this took so long, spring break then I just put it off :P. AHa, the four laws of logic,Something cannot be true and not false. Correct? Now you can prove, logically, that something is something by looking at the molecular formula of that compound or whatever, and therefore youve proved that that is what it is.
The whole unbelieviabilty of the bible and religious views is why I don't believe. Many circumstances, all miracles, but could you ask me a more specific question?
@AA32m7io1 "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness"
I profess myself to be wise because I demand factual evidence of things? I am a fool because I don't have blind faith one of hundreds of religions that has no proof whatsoever? Christians, if you will,
@ProofMelody1 If you look at glycolysis, you'd see that it is theoretically super inefficient. All these reactions are the results of billions of years of trial and error. In my opinion, God had nothing to do with this.
@blaggosphere actually glycolysis was handcrafted by the almighty God. JK i don't believe in fairy tales, but anyways correction, millions of years, its the oldest form of ATP synthase in all life forms, but I am pretty sure it is millions...idk whatever
@blaggosphere On a humorous note have you even thought about if glycolysis WAS more efficient that we would see a even great increase in obesity? Scientists are Already looking for way to make our system less efficient. Just two examples are the Atkins diet where by increasing carbs & decreasing fat intake you run the system backwards to use up more ATP, & something scientist tried but had to recall due to safety issue: finding a way to let heat escape instead of ATP formation in ETC cycle.
@ProofMelody1 You obviously have never heard of the Pulsating Universe Theory, it postulates that all matter in the universe condenses down until it cannot anymore then explodes and starts expanding again until the GIGANTIC center of all center gravitational pull starts to pull everything back, and this happens over and over. Kind of like a paddleball and when you hit it the string only allows it to go so far. Say that ur right, there is a god. Why would he care about a single planet? seriously.
@TDWPMegalomaniaTDWP You are right: Why would God care? But He does. He tells us so in his love letter to us: The Bible. In Romans 5:8 of the Bible it says: "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us." From scanning over a few of your more recent posts I get the feeling that you are highly intelligent about biology, etc. and religion. You seem to know about God with your mind, but what is God telling your heart?
@ProofMelody1 and our one planet is smaller than an atom in comparison to our universe. If evolution of glycolysis can happen here, other forms of evolution can happen in another place, agreed? Or are you one of those extremely closed minded Christians? and while we are on the subject, why would god make cyanobacteria to put O2 on Earth so Humans could breathe? He could've fitted that in to the day he created the water. i'm not saying theres no overall god, but not one that cares personally
@AA32m7io1 I don't think all cells use glycolysis, the reaction necessary to make up the proton gradient is sometimes powered by sunlight in plants for example, or by reducing metallic ions in ferrobacteria. Your second question is valid as far as I know though - I can't find any examples of organisms that don't need ATP, and such a high-energy molecule certainly isn't going to make itself on a regular basis.
At the beginning, shouldn't it technically say "the electron transport chain is a series of protein complexes embedded in the mitochondrial MATRIX's membrane"? Correct me if I'm wrong.. I'm just trying to understand here!
You're right, but so is the video. The membrane where electron transport takes place is the membrane between the Matrix, and outside the matrix. The video simply refers to it as the "membrane" which is the only membrane in the Mitochondrion. They might also be called Cristae.
@latinpapi1 FADH2 comes from the Krebs Cycle, where it picks up H. In ETC, it binds to the second complex, releasing H as protons and electrons. Same principle as NADH:).
hmm what about succinate dehydrogenase ( complex II ) isnt that also involved in electron transport chain as it transports electrons from FADH2 to Ubiquinone???
Where do the 2 more electrons that enter into the cytochrome b c1 come from???from another NADH???if so then it means that 2 NADHs give 10 H+ not 1......since 10 H+ can make 3ATPs it means that 2NADHs=3ATPs,but ive read that 1NADH=3ATPs:-(
If the 2e- come from FADH2 then it shud b 1FADH2+1NADH=2ATPs not 1FADH2=2ATP,right?
Where do the 2 more electrons that enter into the cytochrome b c1 come from???from another NADH???if so then it means that 2 NADHs give 10 H+ not 1......since 10 H+ can make 3ATPs it means that 2NADHs=3ATPs,but ive read that 1NADH=3ATPs:-(
If the 2e- come from FADH2 then it shud b 1FADH2+1NADH=2ATPs not 1FADH2=2ATP,right?
@arizorki The H+ are pumped out by the free energy that is released as electrons move across the chain. They create a concentration gradient because H+ increases the pH in the inter membrane space, creating stored potential energy.
The H+ come from glycolysis when NAD+ is reduced into NADH and H+.

I appreciate the offer but prefer to keep these conversations public so everyone can see the arguments being presented by both sides.
And yes, I realize YT's 500 character format is cumbersome for these types of discussions. So just start with the highlights of your rebuttal and we can go from there.

@AA32m7io1I was strongly religous and I know a great deal of the bible, so i am not a typical one-sided i hate god type, i am extremely open minded, but I will turn towards logic and proof before I believe in other humans, because believe it or not people lie, even during biblical times. If you believe in miracles thats fine, but theres always a scientific cellular/chemical explanation, and have you ever thought that the stories in the bible are just overexaggerated to make a good story.
TDWPMegalomaniaTDWP 11 months ago
@AA32m7io1 possibly those rocks could have been placed at a totally different location then, then swept deep under, but still retaining their oxygen. But oxygen from where...shit. But just because we don't know something doesn't give us the right to give God the credit. We used to think god made the sun come up and down. I could write pages on this subject so I'll stop here and tell me what you have to say about it.

@AA32m7io1 Our atmosphere was not always rich in oxygen, sir. It was composed of Hydrogen and Helium. Note first oxygen appeared in oceans and atmospheres 2500 MYA.alright, I just read that article, and I admit, that is EXTREMELY interesting, i'm bringing that in tomorrow...wow. This is just me speaking here, thinking of explanation, the plates obviously have shifted a great deal and

@AA32m7io1 Nitrogen fixaters change N2 to NH3. CO2, N2, and water is all that cyanobacteria require. I have no clue what you are talking about with oxygen. . And your deep sea rock theory is also backed up with information and theories like all our oxygen and water got here from asteroids colliding with earth that were rich in those compounds. lol fail.

@AA32m7io1 120 period time frame, now you can't say that all of this information collaborated together is 100% accurate. Now I respect all religions and have nothing against god (God) but frankly, It just isn't logical.Now, I would like you to view a video of mine..."Christopher Hitchens - Christianity is Immoral". Now what you said," How did amino acids link together with somuch oxygen" WTF man??Nitrogen is essential for the production of amino acids and nucleic acids in organisms.

@AA32m7io1 "brainwash" their congregation, being that they bring them and tell 5 year old kids their ideals. And it goes from there, with that person obviously believing what he has been brought up to believe. My truth is not in "unrighteousness" but in facts. I am not trying to minimize god, just explain. The bible leaves no room for explanation. Will I go to hell because I believe in facts and not what the Bible says? The Bible was written by dozens of people within about a

“Now I respect all religions and have nothing against god (God) but frankly, It just isn't logical.”
Speaking of logic, where do the Laws of Logic come from? Since they are not physical in nature, what empirical evidence do you have that proves their existence?
Also, where do the Laws of Logic fit into Herbert Spencer's five categories of time, space, matter, force and action?

I have no reason not to take you at your word. Could you please tell me what empirical evidence caused you to reject the Bible and religion?
“have you ever thought that the stories in the bible are just overexaggerated to make a good story.”
Never.
AA32m7io1 10 months ago
@AA32m7io1 Hey sorry this took so long, spring break then I just put it off :P. AHa, the four laws of logic,Something cannot be true and not false. Correct? Now you can prove, logically, that something is something by looking at the molecular formula of that compound or whatever, and therefore youve proved that that is what it is.
The whole unbelieviabilty of the bible and religious views is why I don't believe. Many circumstances, all miracles, but could you ask me a more specific question?

@ProofMelody1 If you look at glycolysis, you'd see that it is theoretically super inefficient. All these reactions are the results of billions of years of trial and error. In my opinion, God had nothing to do with this.
blaggosphere 11 months ago
@blaggosphere actually glycolysis was handcrafted by the almighty God. JK i don't believe in fairy tales, but anyways correction, millions of years, its the oldest form of ATP synthase in all life forms, but I am pretty sure it is millions...idk whatever
TDWPMegalomaniaTDWP 11 months ago
@blaggosphere On a humorous note have you even thought about if glycolysis WAS more efficient that we would see a even great increase in obesity? Scientists are Already looking for way to make our system less efficient. Just two examples are the Atkins diet where by increasing carbs & decreasing fat intake you run the system backwards to use up more ATP, & something scientist tried but had to recall due to safety issue: finding a way to let heat escape instead of ATP formation in ETC cycle.

@ProofMelody1 You obviously have never heard of the Pulsating Universe Theory, it postulates that all matter in the universe condenses down until it cannot anymore then explodes and starts expanding again until the GIGANTIC center of all center gravitational pull starts to pull everything back, and this happens over and over. Kind of like a paddleball and when you hit it the string only allows it to go so far. Say that ur right, there is a god. Why would he care about a single planet? seriously.
TDWPMegalomaniaTDWP 11 months ago
@TDWPMegalomaniaTDWP You are right: Why would God care? But He does. He tells us so in his love letter to us: The Bible. In Romans 5:8 of the Bible it says: "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us." From scanning over a few of your more recent posts I get the feeling that you are highly intelligent about biology, etc. and religion. You seem to know about God with your mind, but what is God telling your heart?

This has been flagged as spam show
@ProofMelody1 and our one planet is smaller than an atom in comparison to our universe. If evolution of glycolysis can happen here, other forms of evolution can happen in another place, agreed? Or are you one of those extremely closed minded Christians? and while we are on the subject, why would god make cyanobacteria to put O2 on Earth so Humans could breathe? He could've fitted that in to the day he created the water. i'm not saying theres no overall god, but not one that cares personally
TDWPMegalomaniaTDWP 11 months ago
@AA32m7io1 I don't think all cells use glycolysis, the reaction necessary to make up the proton gradient is sometimes powered by sunlight in plants for example, or by reducing metallic ions in ferrobacteria. Your second question is valid as far as I know though - I can't find any examples of organisms that don't need ATP, and such a high-energy molecule certainly isn't going to make itself on a regular basis.

At the beginning, shouldn't it technically say "the electron transport chain is a series of protein complexes embedded in the mitochondrial MATRIX's membrane"? Correct me if I'm wrong.. I'm just trying to understand here!
ipsamtrash 11 months ago
@ipsamtrash
You're right, but so is the video. The membrane where electron transport takes place is the membrane between the Matrix, and outside the matrix. The video simply refers to it as the "membrane" which is the only membrane in the Mitochondrion. They might also be called Cristae.

@miphisto55 nope. there are two membranes. and Cristae refers to fold in the inner membrane. Cell anatomy fail.

What about FADH2 and where it enters ??
latinpapi1 1 year ago
@latinpapi1 FADH2 comes from the Krebs Cycle, where it picks up H. In ETC, it binds to the second complex, releasing H as protons and electrons. Same principle as NADH:).

Where do the 2 more electrons that enter into the cytochrome b c1 come from???from another NADH???if so then it means that 2 NADHs give 10 H+ not 1......since 10 H+ can make 3ATPs it means that 2NADHs=3ATPs,but ive read that 1NADH=3ATPs:-(
If the 2e- come from FADH2 then it shud b 1FADH2+1NADH=2ATPs not 1FADH2=2ATP,right?

why are the hydrogen ions pumped to the intermembrane? and where do they come from?
arizorki 1 year ago
@arizorki The H+ are pumped out by the free energy that is released as electrons move across the chain. They create a concentration gradient because H+ increases the pH in the inter membrane space, creating stored potential energy.
The H+ come from glycolysis when NAD+ is reduced into NADH and H+.
