then it's wrong, because it's 30 or 32 ATP

I've read in some books and they said that the difference between 36 ATP and 38 ATP is based on the prokaryotic and Eukaryotic cell

This is what i meant. why? because i know otherwise :D Even in the human body, you can find both kinds of cells, depending on which methabolic pathway the reactions follow. i think Dr.Stein gave an example...

Um, quite confused actually but let me write it down once more.
we get 2 ATPs and 2FADH2 from glycolysis = total 6 ATPs.
we get 2 ATPs, 8 NADH+H and 2 FADH2 from Krebs = total 30 ATPs.
if all of the ATPs are summarized, it will be 36 ATPs right? (it's in eukaryotic)

If in prokaryotic:
we get 2 ATPs and 2 NADH+H = total 8 ATPs
we get 2 ATPs, 8 NADH+H and 2 FADH2 from Krebs = total 30 ATPs.
if all of the ATPs are summarized, it will be 38 ATPs right?

so?
I know, I haven't reach the more complicated stuff of BioChem but at least..is these right?
Q: Why are chemists great for solving problems?
A: They have all the solutions.

my friend, generally, for making 1 ATP cells have to use 3 H+, 2 electrons can pump 10 protons, further information in the book<<color atlas of biochemistry>> chapter of ATP synthesis

The transporter used in electron transport is NADH; Krebs cicle generates 6NADH; because to ossidate a glucose molecole are nedded two Krebs cicle, the total production of NADH is 12.
In the elctron transport every NADH produces 3ATP; so after electron transport are generated 36 molecules.
The total balance of aerobic metabolism is 38 ATP (2 ATP from glicolisis + 36 ATP from electron transpor = 38 ).

I need to figure out how many molecules of Nad+ are reduced to form NADH for each molecule of pyruvic acid that enters the Krebs Cycle?

google images for "krebs cycle" and you will get your answer

i m gonna answer victor's question..
actually each NADH produced in glycolysis....produces 2 instead of 3ATPs...and it is called substrate level phosphorylation...because oxygen is not involved in it....hence the 2NADHs produced in glycolysis produces 4 ATPs...and i think total ATPs produced in glycolysis are 6...now u can easily get the result of net gain of 36 ATPs instead of 38 ATPs...ok...
