Question

How many ATP's are produced by complete oxidation of PEP?

Answer 1

Total 38 ATPs are produced by complete oxidation of one molecule of glucose. Out of 38 ATPs, glycolysis produces 2 ATP, Kerb's cycle produces 2 ATP and electron transport chain produces 34 ATP. In glycolysis, one molecule of glucose produces 2 molecules of PEP (phosphoenolpyruvic acid). Also, 2 molecules of ATP are produced from conversion of 2 molecules of PEP into 2 molecules of pyruvic acid.

Thus, complete oxidation of one molecule of PEP produces 19 ATP molecules.
