Professor Fink explains CELLULAR RESPIRATION (Part 4); Glycolysis & Fermentation

[Saac06]

During fermentation, when the NADH transfers its H+ back to pyruvate forming lactate, what happens to the NAD? Is it "free-floating" in the cytoplasm, is it stored, is it converted into something else?

[scarablarg]

made 4 years ago and still useful

[CallMeJEFT]

Thank you :D

[apuffin97]

I hate chemistry. But your videos make me less likely to fall into a coma as I study cellular respiration. :D btw I think your diagrams are fantastic.

[jolanwix]

I am in Med School, and you have NO idea how much these videos have helped me. Thank you SO much, Professor!

BTW, when I see his run at 8:07, my mind automatically starts playing the Guile theme song...its quite epic, actually.

[ohioSPIRIT]

great explanation!

[9klam9]

OMG MAN !!! THANKS!!! THE BEST.

[brightnessQQ]

holy shit this guy saved my life



[alpower384]

Thank you so much for making things clear!

[SophiaFreakinFields]

Can you just become my teacher? Thanks.

[celibean55]

You are am excellent professor. I like that you recap the information you covered previously. I am currently taking biology and felt confused after my in class lecture. So thank you for providing your lecture.

[phoenixpineapple1]

VERY good! I like how you briefly go back every once and awhile to repeat what you have taught, it really helps me stay on track and not get lost. I think i'll be ready for my micrbiology quiz tomorrow :)

[2rushton]

teach me how to fink

[qrais]

you are the best prof. I have ever listened to in my life it is 3AM in Norway and I simply can not stop watching... it is so interesting wow thank you so much sir

[tusharrable]

I am a grade 9 student. I had problems understanding Glycolisis but you made it so simple and easy that now it seems to me like quarters and a 10-dollar bill. I am Tushar from India. Thanksss

[MrLoveHate28]

Thank you soo much for this video. I have a test in a week and I was very unclear regarding this module. But now I am confident. Thank you and Bless you.

[xol0veme0rleavemexo]

man I wan him as my bio teacher

[jeru333]

HEY PRO FINK! EXCELLENT VIDS!! WHICH VITAMINS AND MINERALS are MOST CRUCIAL IN THE PRODUCTION of ATP?

[elsenorify]

i had to login just to say dis... prof. fink, u the best teacher... this was so helpful thank u!!!!

[blondelifeguard10]

thank-you so much!!!!!

[xTLOWWW]

you are the best!!! this helped so much!

[TheBinks18]

YOU'RE AMAZING!!!! THANK YOU

[onyxfig]

Professor Fink, I am sure you realize this, but you skipped a HUGE portion of the glycolysis step (the gazillion enzymes, the several individual steps of phosphorylation,etc).

[sillypanties100]

incredibly well organized. thanks p fink

[billy1496]

YE YE FINK TELLEM'

[Estefani104]

I am sophomore in college taking Biology 189 and I can say I understand you a lot more than that very expensive textbook we had to buy! thanks! keep on going!

[aali1005]

THANK YOU!!!! I was dying without knowing about Cellular Respiration!! You rock! I wish you were my Professor! Thank you so so so so so so so so much!!! :) HUGZ!!!

[xbullshizzy]

helping me pass paramedic class, thanks alot prof. fink!

[nidz30]

Dear Professor,

You're just awesome. Thanks for explaining everything in detail.

U're a great teacher. You don't assume that students "already know" the "simple stuff", and you explain every single thing. Your analogies are superb. Thank goodness for you. And by the way, that's a cute slap.

[gemjernae]

Thanks a lot! I haven't taken science since tenth grade. Now that I am approaching my final year in college, it has become very difficult for me. I have been lost this whole quarter in trying to COMPLETELY understand cellular respiration. Now that finals are around the corner, my boyfriend suggested I try finding some assistance on youtube, and here you are! Thank you so much, and I look forward to learning more from your videos.

[donkorleon21]

By far the BEST video and helped me so much. Thanks!!!!

[AnimationGenius]

I LOVE how you teach! I can't believe we are learning this stuff as a freshman in highschool, but my teacher skips little parts of the lesson, because he expects us to know. but you know what? I don't know all the little details. and the details are what bundles everything together. However, you teach the details, without wasting too much time (my teacher's main concern). you are excellent, I wish I have a professor like u in 4 years when i go to college :D GO PROFESSOR FINK! you are amazing!!!!

[MrGreenvision]

Awesome! Again, another simple explanation.

[CoolSciTeacher]

Professor Fink thank you for your erudite explanation. Your explanations are so clear!!!

[megustameganlomania]

Thanks so much for posting these...I am in the process of studying for my HL IB Biology test and my AP Biology test, and I have been scared to death...these processes have made NO sense to me until now. :)

[chikitadulce]

Thank u so much Professor Fink! You explain VERY well! This really helped me :)

[MarjorieBel]

Starting from the beggining, those 2ATP used to break apart the glucose into 2 pyruvate, where does it come from?

[xxNeemixx]

wow!! thankyou so much!!

[rockya13]

lol at 2:54 to 3:00

[hupper12345]

Wow you are so amazing!! this makes it so much easier for me and enjoyable... it was just so stressful reading from the text book endlessly trying to understand this process..THANKYOU SO MUCH...I LOVE BIOLOGY!!

[babubhaipotli]

Thank you dear sir. You are the best

[VariousFruits]

Fink > most professors

[brownmolasses]

GOD bless u. YOU'RE the BEST. hugs*

[love4noreason]

Dear Professor Fink, please make a video on photosynthesis too you are an awsome teacher by the way. Thanks again

[2xWoot]

You keep amazing me! Thank you! This world needs more people like you, people who are willing to help others. XD

[trakapoker]

professor fink ... u r a star.. WELL EXPLAINED...!!!!  thank you thank you...

[fromme93]

Thank you so much.

I am a junior in high school taking AP Bio and you saved my life!!

Everything is so clear, and you explain the little details that my textbook seems to think I already know.

Thank you, thank you, thank you!!

[professorfink]

Thank you for your kind words.

I appreciate it very much! -- professor fink

[withloveforever10]

yep! I have a major test tom......

[notw009]

wow!! Thank You soo soo much! You are a great Professor! Clearly driven by Passion! God Bless your work!

[limeOjello]

I was told that the purpose of NAD is to transfer electrons, not hydrogen. I'm sorry if this is a dense question, but I don't understand what NAD does. Agh! Science will be end of my college career...

[professorfink]

NAD plays a role in the movement of both electrons and protons (and since 1 proton + 1 electron is called a "hydrogen atom", it is reasonable to say that NAD is involved in the transfer of hydrogen atoms). -- professor fink

[Linh03]

I wish he was my micro professor.

[INSOMNASTALGICAL]

I really don't see any discrepency between this professor and the handful I had before, pretty much words it in a way that the next professor or teacher is giving it... The only thing I really liked is the fact that you can pause the video when he is giving the lecture, and he doesn't seem impatient when you need him to repeat something!

[deenyul]

Where does this man teach I need to transfer

[annakolod]

The same here, he's saving my live !!!

Awesome Professor !!!Thank You so much !!!

[volleyballchick1338]

Great video! Lots of help, much appreciated!

[Haitianpbh]

i got a 90 on my test because of this man....come teach at brooklyn college

[Vybertastic]

I wish he was my teacher :'-(

[gbodkin1]

for some reason this vid isn't loading :( by the way...you're amazing dr.fink

[ewoman1147]

WOW. What an amazing teacher, he makes my prof seem like he has an IQ of a cabbage

[Knappy42]

This guy is awesome! Clear and quirky....beautiful!

[TheExPlOiTeDOne619]

I know I'm seriously happy I saw this... I got a final tomorrow, probably gonna pull an all nighter -_-

[Imbrickle]

*applause* This guy is good.

[Imbrickle]

One note, current research suggests that lactic acid does not directly contribute to muscle fatigue as is commonly believed. See Allen, Lamb and Westerbald, andRobergs,Ghiasvand & Parker.

[Pfeier]

excuse: what does PGAL mean?

[pwrtecman]

PGAL = Phosphoglyceraldehyde

[Pfeier]

thanx

we learnd it with it`s isomere: glycerinaldehyd-3-phosphat

[ax2kool]

Hot Potato Hydrogen Atoms! What a name! I'm gonna use this on my exam LOL

[LTadrift]

Woohoo!! I'm starting to love glycolysis :D

[Keirmann]

simply amazing

[greencoveredbridge]

Unbelievable. my teacher just throws a blurry outline up in the projector and recites the outline, each line, in monotone, he explains NOTHING. I wish SO MUCH I had a teacher like you. I can't even imagine how great it would be go go to a class like this all semester.

[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

[uqbauqba]

I AGREE. i hope u live a millions years and teach more ppl.

[mattuk180586]

Wow, I wish you were my professor! Mine sucks. You have helped me soooo much! thanks

[mentalliberation]

In part 3 he mentions Anarobic respiration happens with oxigen, and aerobic respiration without, here he says that aerobic respiration happens if oxigen is present!!!

[professorfink]

An-aerobic = without (air) oxygen

Aerobic = with (air) oxygen

[mentalliberation]

I know, i`m just pointing out what you said in part 3 maybe you didnt notice, but it is obvious that you Know, in part 4 you said it right!!

aerobic= with oxigen

anarobic= without oxigen

I`m just a student, your class helped me for my test, thanks!!

[filmchick41]

Response to mentalliberation (1 month ago) Actually I just finished watching Part 3 and I went back and rewatched the part about Aerobis & Anaerobic and he said it correct in Part 3.= Professor fink said Aerobic with oxygen & Anaerobic without oxygen. He even explained how "an" in front of a word means without. I too wish I had this professor, mine is really too hard to understand.

[maureen6281]

You are a great teacher, and you are doing a great service to post this video on you tube.

[udontnome7211]

i agree with "mchyker" love this videos!!!! your a great teacher!.... cna i make a request for a video? im working on DNA and im kinnda lost....do ya think you can help?

[FTWandCTM]

part 3 is gone :( kinda lost now

[mchyker]

many people with such great explaining skills would sell their dvd's to make money. Giving it for free through you tube is something a true educator would do.
