Professor Fink explains CELLULAR RESPIRATION (Part 6); Krebs Cycle; Electron Transport Chain

[SolsticeSteph]

@grewal02 I'm in university stuck learning this all over again. It is pretty much he same. Mind you, I'm not a biology major so I can't say for sure if there is more depth to the subject or not. You will find your first year of university is a large and compressed review of high school for the most part. They need to make sure every student is on the same page before moving on.

[dowlinginvestigation]

You are awesome Dr. Fink!!!!!!!!!!!!!!!!!!!!!!!!

[alz123alz]

Beautiful, Beautiful, Beautiful, Bravo. I have never heard this biochemical process so well explained.

[MasaZumba]

You're wonderful!!!!! Thanks!!!!

[2rushton]

teach me how to fink

[sweetylova7]

like this if you thought he was going to say FAD picks up two "hot potato" hydrogren atoms after talking about the NAD :)

[tusharrable]

Thankssssssssss. This was the best bio video I have ever seen in my life

[blkrican2009]

omg I would be sooo pissed off if my teacher would be doing all of that hand clapping and hitting the board. I am trying to take a nap.

[abadeau91]

My Biology I final exam for college is tomorrow morning and it's mainly on cellular respiration! Professor Fink saved my butt! I practically fell asleep when my professor tried to teach it to me! This videos were so easy to follow and stay awake during. Everything is so simple now, I'm sure I'll pass. Thank you Professor Fink!!!!!! :) :) :)

[drunkdrftr]

Very good professor, excellent study help for me.

I especially like the way you relate it to normal examples in life, and how you repeat important information twice, so it really sinks into someones brain.

When you repeat something, its analogous to a student highlighting something in their textbook!

[samrinahmed]

thanks a lot prof.fink..i am really grateful to you that you provide me super knowledge about ETC.I am the teacher of grade 11-12,and i was really confused,how to taught this topic but u really solve my problem.THANK YOU AGAIN

[LupoBHS]

Karate CHOP! = Co2

[jakeo96]

hahah now i undertand why he kept saying hot potato throught his lecture i was like what the hell is this dude talking about? we hav potatos now?

[1ove1ife29]

I've had 6 science classes since high school that have involved the krebs cycle in the curriculum... four and a half years later, I figure it out on youtube :) hah I love this professor!

[dmoo3666]

OMG, OMG my A&P teacher was an exercise/physiology nut. I cannot believe how incredibly simple you made this all seem. Unbelievable. You da bomb.

[dmoo3666]

Okay I am totally in love with this guy. You are so cute with the whole hot potato thing. Hilarious but I get it. Also, I have been going literally crazy in trying to understand NAD+/FADH, but you merely said that they are in vitamins (niacin and riboflavin). Thanks.

[Zsaw8]

This is a hell of a help for me!! Thanks Professor Fink!!

[moglycho]

Wow~Awesome explanations both Organic chemi and Anatomy cat dissection!

May Professor Fink live long and help so many students like me understand clearly forever and ever. Thank you so much!

[ExNihiloJimmy]

makes me want some sugar :P

[nitz47]

professor fink...you are the best...

actually the calvin cycle in photosynthesis is quite confusing!!!

everybody would like it if uyou could explain it!!!thank you

[SuperMaiwand]

come on, 8 NAD are produced in creb's cycle not 6 i am sorry, in aerobic resp--- 36 ATP are produced.

[ceci2802]

Prof. Fink you are wonderful!!! thanks so much for making this hard process easier to understank. Really thanks so much!!!

[snes06]

@ 8:05 FUCKING CELL PHONE are you kidding me! I hate it when this happens in class and now here?!!? We can't get away from it, stupid cellular age...

[babubhaipotli]

Man, Thank you so much

Really.

[skittlesx0xo]

Mr. Fink, i love you.

you're amazing.

[Deat401]

Nice ringtone :o

[ThisOleGem]

lozzenger, - im going to take some tongs... ah got my exam on monday, and yay for combineng revision with youtube, it makes it more bearable. :)

[MrSteveban]

Ur the man Fink. I have my my 9th grade bio honors midterm tomorrow and this really helped me

[haakonss]

HOT POTATO!

[salvatoredamon]

hooot potatooooooo

[floppycooldog]

thanks vary helpful !!

[kiwichip]

Thank you so much! I didn't really get the krebs cycle before, but now I do!

[KoGgirl103]

I'm in 9th grade and the way he explains this is super easy compared to the way my bio teacher explains it. ugh...i wish he was my teacher.

[dalooloo28]

ME TOOO

[drumjoba]

thanks for this value information. with out it i woulld never actually understand this process. and the karate chops kept me awake through the whole explanation.

[POLO11220]

a cell phone in 7:55?

[AndresDX1]

haha imagine if he breaks his hands when he was using his bruce lee karate chops

[abettername]

you have given me hope for my midterm.

[ThatDifferentGuy]

I love how he smacks his hands to prove his point. Good learning tool!

XD

Thanks !!!

[Xelastic]

Knowledge is Power, Thank you for sharing it.

[megaaantron]

you're awesome, I watch you and learn...my teacher is awful

[Whitesugarify]

U r such a good teacher!!! thanks you very mcuh ^^

[SurgeonGen3ral]

Hot Potato Hydrogen Atoms.

[hehsaan]

that guy smacking the board is fucking genius

[zznarcolepsy]

These hot potato Hydrogen atoms... Do they exist outside the potato plant?

;-)

[rapidrabidrabbit]

Hyaaaaa! 0:04

[Purl82]

lol

[Purl82]

thank you professor, i'm taking a bio class at the same school where you teach and my teacher is awful! u made it so nice and clear, got the whole picture+ the details. thanks!

[GetItRight222]

I'm using this for my lab report hehe

[Deat401]

Nice ringtone.

[nat5484]

this was really helpful! :)

[teamkilla]

I really like your energy and teaching skills :) However, one improvement could be to have the structures and complete cycle details (perhaps predrawn due to time limitations)... otherwise it's just a suming up of the end results, but doesn't explain how and why it happens (except for the "you need oxygen" part) ;)

but again, really good!

[nodamnnickname]

lol he slams the board and his hands so hard

[sylviabombs15]

his hands feel no pain

his karate chops put chuck norris to shame

[nodamnnickname]

nobody puts chuck norris to shame

[plnoyology]

hot potato!!!!

[albatros178]

you really are doing a great job

even i am a teacher i have learnt a lot from your explanations and analogies

can you please tell us where to find these lessons so as we can print them out

one more time thank you

[atillathegun]

Anyone count how many times he said hot potato hydrogens?

[jollyfellow25]

so well done, congratulations !!

[chumma25]

The videos were very helpful and informative! I really enjoyed them! I have always hated biochemistry!! If the lectures were like yours I probably would have had great interest. I am glad I came across your lectures i understood them soo well!! Thank you SIR!

[marnus89]

I enjoy the videos very much, preparing for exams thanks!!!

[cuteladyness]

Thank you for posting these videos. These have helped me more in a few hours than a couple of lectures at my college.

[kikkom4n]

has anybody told you that you look like a little like steve jobs?

[thierryosman]

he does look like steve jobs

[kpaul00]

i have a problem with this, FADH2 is not generated in the krebs cycle. FAD is a prosthetic group in the enzyme Quinone dehydrogenase that takes succinate and converts it to fumerate. You actually get UQH2 generated (ubiquinol). This acts as the carrier for H2 atoms

[nkaminskiy21]

Thanks for explaining how we got the 10 NADH2s. It was so fricking frustrating because I kept on coming up with a total of 8 because I didn't take into account the transition process.

[dee2x]

yan ang tcher! talgang may emphasis ang bawat explanation! ayus!

[greencoveredbridge]

you're a great teacher. thank you.

[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

[r0drigues85]

@professorfink thanks a lot and congratulations!

[grewal02]

@professorfink

if you learn this in univeersity and i already learned it in high school then what do u learn in university , can it go into any more depth , i have learned the enzymes for each steps of everything on krebs and glycolysis

[anonymous345]

@grewal02

You can also memorize every intermediate substrate, what happens to them, their structure, etc

[vpxg0tryc]

doesn't NAD+ pick up only 1 H+, forming NADH, not NADH2?

[Spikey2883]

Fantastic! I'm a student trying to complete my first 2 yr. degree at Houston Community College in TX. I appreciate your superior explanation of the Krebs Cycle!

~ A.H.

[anniex18]

is it true that the co2 formed in the krebs cycle gets its carbons from oxaloacetate and not from the pyruvate or acetyl CoA?

[berlin45ers]

awesome!

I THINK HE LIKES HITTING THINGS....

[Spot7Zero2]

Ha! Ha! Yeah, I too noticed he likes hitting things. :D

[prec1ouzlov3]

this was extremely helpful! thank you! excellent!

[nastern100]

superior explanation!
