Professor Fink explains CELLULAR RESPIRATION (Part 2); ATP, Role of O2

[s0natine]

Thank you so much, Professor!

[isnasucks]

The best professor ever!

[RobFS1]

@professorfink The time just flies by watching this, because of your enthusiasm.

[grimartificial]

This is the clearest explanation of cell respiration that I have ever seen/heard.

[scarablarg]

lol OIL RIG. i see what you did there.

[mademoiselleLoveGame]

Awesome explanation.

[jorritje1]

This theme in the biology is like chinees for me.. and I think for a lot of people.

but you professor Fink, you are just amazing. you just translated it and made it look like 2+2=4.

thank you so much, and keep up the good work!

[pat28]

I appreciate you making these videos, they are really great!

[mcpl77]

awesome!!!! Thank you Professor Fink

[hdinh001]

I feel like even with biology, microbiology, biochemistry, I have never understood this as I do now. I wish I had known about this when I studied in undergrad!

[otamanlvhs]

Wow,I can't believe I actually understand this stuff now!Before your video,I thought of myself as a dumbest thing ever.

[SpaceBandit666]

This is great, he makes it so easy to comprehend!

[phoenixpineapple1]

I can't tell you how helpful this has been! Keep doing what you're doing, thanks!!

[2rushton]

teach me how to fink

[IAMATOFFEE]

you remind me of brick tamland in anchorman

[munozochago]

Your awesome!

[hannahpark04]

Professor Fink! Where do you teach>??

[TheJdawg1234]

lol i think someone was falling asleep when he clapped. well i hope i do good on my test tommorrow.

[anfro18]

I once learned that IF you delete your sources of simple/complex sugars, your body turns to fat, which has roughly 2X the energy then a carb (due to high number of C-H bonds) I also learned that if you have no fat to breakdown for energy, your body will then turn to proteins (amino acids) which can cause acidity in the blood. Are all these processes of breaking down food considered Cellular Respiration?why carbs as #1 choice? Why not fats since they are packed with more energy?

[anfro18]

@anfro18 Having said this, I've never had a teacher this good/knowledgeable so correct me if I'm wrong :)

Please and thank you in advance!

[santm092]

I could kiss his feet for letting me understand this

[davmul1980]

Great job =!!!!! I wish I was in his class! AND BY THE WAY WHAT IS THE COLLEGE NAME YOU ARE TEACHING AT?????????

[rezaeijavan]

who were those 2 people who disliked?

[Realnofriendofbush]

I get as much joy out of the comments as I do prof finks lecture my inner Childs

Laugh came out a few times - what a legend hey :)

[benjalame]

awesome video !! this is the first time i get science

[jkimt08]

WOW this is great! my teacher is good but he totally jumped into glycolosis without even going over this kind of overview so I didn't really get what the heck glycolosis was really for...but now I do!

[asheyu]

this guy is a LIFE SAVERRRRRR

[austin4ski]

why am I paying 50,000 a year for school when stuff like this is on youtube!

well done!

[hyperlegs499]

@austin4ski 50000???o-0

which school do u go to exactlyo-0

[MrSharpAss]

I wish my chemistry teacher is like you

[LDChalem]

Hi Professor Fink!!! If Homo sapiens get 34 ATPs from OP and only 2 from glycolysis, then don't you suppose it's more effective to get your raw fuel from fat, which is a substrate for Acetyl COA, which is a substrate for OP (given that you also get the essential amino acids)? Would you agree that we never need to eat anything that breaks down into glucose? Thx... - lc

[blisskiss23]

I am studying for IB Biology and I was so frustrated that the textbook didn't explain anything properly. Watching your video here released all my stress and now everything makes PERFECT sense. Why can't my textbook explain like this ?

[tanman2468]

hahahaha!~!! It spells OIL RIG lolol

[MrGreenvision]

Freaking Brilliant explanation! Where were u in my college years. I could have amount to something. :*)

[wespin09]

Thanks professorfink, I have my midterm today and watching your videos about cellular respiration made it much easier for me to understand the whole precess.

[dwbaird13]

Bless you Professor Fink!

I may not remember everything right off the bat but this makes a lot more sense now.

[xweichin]

thank you so much for this! I'm using a review book, but i find it so much easier when someone's explaining it to me. AP/SAT II bio test is coming up, and the cellular respiration is by far the hardest chapter to understand (at least that's how i feel).

[rockya13]

this guy explains it the way i should be explained. quality

[christina1495]

Thank you so much! This makes sense!

[hupper12345]

you are just amazing..thanks for helping us students! Just so helpful!! ..Thanks..Thanks..Thanks..Than­ks..Thanks.. :)

[babubhaipotli]

Thanks!!!

[rlquire]

I've got a Micro test in two days and have been so confused. Now, I'm not! Thank you SO much!

[jennaykimmay]

Thank you so much! I love your videos and they've helped me a lot! :)

[oddn]

fascinating, i understand it so much better now, thank you! :)

[Mcleigh]

I love you Professor Fink.

[agretha]

Hi Professor!

Thank you very much for your vids. Theyre not only amazing but w-o-n-d-e-r-f-u-l. Finally I do understand EVERYTHING that I should have understood during med-school and didnt. :) Thanks a whole bunch for your talent and for teaching here.

[mscab2]

Amazinggg

wish you were my teacherr

[1k1ll3rp0ll0]

:O very interesting! i have a deeper understanding now, thank you so much is very interesting, but one question: why if NAD is in fact niacin can be used to make the body release waste material? (i have seen people taking niacin and turning red as hell,jaja) how does this process occurs, or is it related to the cellular respiration?

thank you so much YOU ROCK! :P

[hitdoggie]

What a gift he has for teaching.

Other Ph.D's should note.

[Stavrosnco]

I'm a senior in Molecular Biology and this has got to be the clearest understanding I've had of any of these topics even after 4 years of study.

[sylviabombs15]

6:12  his pimp hand is strong...

7:56 he demonstrates how he smacks the shit outta electrons and hydrogen atoms

[ThatDifferentGuy]

Lol he probably pimp slaps bad students and his hoes if they dont pay on time!

XD

[echeverriaconsuelo1]

Dr Fink thank you very much for your illumination and clarity! You are a mitzvah

[lilmissdani86]

great videos, clear and concise explanations without any additional/confusing useless information. Thank you very much Prof Fink :)

[tehpownlawl]

When does NAD turn in to NADH+?

[nejetyhw1]

NAD+ is floating around in the cell and picks up a hydrogen to make NADH.. ....NAD+ is like a carrier for hydrogen that brings it to the electron transport chain and will inturn make ATP and H2O .. i hope that helps

[1k1ll3rp0ll0]

:O ty

[ThatDifferentGuy]

Actually its NAD+ and it turns into NADH when it takes on hydrogen ions and electrons.

[Diana0155]

Professor Fink, you are exceptional. You may have just saved my life, as I nearly fell asleep watching my teacher make a half-hearted attempt at explaining this topic. You actually seem to care. THANK YOU.

[Deagra940]

thank you. i very much appreciate these videos- my bio book just does not cut it.

[desidol22]

u r amazing! where do u teach??

[alysiamarieelizabeth]

thank you sooooo much!

[grapecoon]

professer fink,

you make science a piece of cake. Thanks

[jesskeepinon]

Thanks for posting these lectures! Taking Intro Biology online and needed the audio/visual to fully grasp this concept. Love "OIL RIG"! Big help...

[utube2diwerl]

i so wish my biology teacher was like this. i mean he's not that bad but professor fink is the real deal.

[SexyNeverLeft69]

LOVE THIS! =D

[jollyfellow25]

well done.

[gomety]

excellent!

[jww047]

I love how he repeats things and states the purpose of the process a lot during his explanation, it helps so much.

[junilda70]

Hi Sir Professor Fink,

the vedio you make is very good i like very much to se, i have go to school here in Danmark, but i have a little problime my homework this is a kind of photosinthisize and a greenhouseeffekt i hope you can helpme thanks

[Dexduzdiz]

these videos are SOOOOO GOOODD

[jmkeller]

7:56 - man, it's amazing how he can command a slap like that so quick; by the way, GREAT videos. Thank you, Professor.

[vjsingh101]

lol i love it when u slap ure hands together, it keeps my attention. and yea I too wish my biology teacher was like u.

[123gloopers123]

Brilliant. I wish my Biology teacher was like this!

[varkomdragon]

If you can make ATP from glycolysis, what is the point of oxidative phosphorylation? Is it to provide the ATP spark needed for glycolysis?

[ArtOfPhire]

The process of oxidative phosphorylation in the following processes of cellular respiration acts as a catalyst for the chemical reactions occuring in the Electron Transport Chain that allow for the formation of ATP.

In simpler terms: Yes. It provides the "spark" or the phosphate molecule needed for ADP to become ATP.

[professorfink]

Technically, each H atom is 1 proton (H+) and 1 electron. So, 2 H atoms = 2 protons and 2 electrons.

Each NAD+ picks-up 1 proton (H+) and 2 electrons, becoming NADH. The other proton is H+.

So 2 NAD+ plus 4 H becomes 2NADH + 2H+.

For simplicity, I prefer to say 2 NAD become 2 NAD-H2

[CaptainDuck1304]

@professorfink

During glycolysis, where do the two hydrogen atoms that react with NAD+ come from? (i.e. in "NAD+ + 2H ---> NADH + H+" which molecule is oxidised to give the 2H?)

[gypsyeyes1230]

Excellent !! I love your use of analogies in order to help explain it better. You have a way of gaining a person's attention through your articulation and enthusiasm. I wasn't bored one bit and was intrigued by the whole thing. Thankyou for making it fun to learn this!!!

[Essincy]

you are the best teacher i have ever been taught by. seriously.

thank you so much!

god bless!

[barnamah]

the best teacher ever. thank you

[JaimeHill88]

Professors like you remind me why I am a Biology major! This was so extremely helpful! Do you have any videos on subjects other than cellular respiration?

[dbsk06]

omg you are so cool. i learned more from this one video than i did in a whole month at school
