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

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

PROFESSOR FINK GOT ME AN A ON FINALS (:

[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?

made 4 years ago and still useful

Thank you :D

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]
