Excluding both glycolysis and the citric acid cycle, how many ATP\'s are theoret

Question

Excluding both glycolysis and the citric acid cycle, how many ATP's are theoretically possible from oxidative phosphorylation as a result of the oxidation of 20 pyruvate molecules to form 20 acetyl Co A molecules? Show your work.

Explanation / Answer

glycolysis =2ATP per glucose. half of 20 ( because 1 glucose breaks into 2 pyruvate) = 20ATP,20 NADH Oxidative decarboxylation of pyruvate 2 NADH Citric acid cylcle = total energy yield from one glucose molecule (2 pyruvate molecules) is 6 NADH, 2 FADH2, and 2 ATP = 20 ATP, 60 NADH, 20 FADH, eletron transport chain = The gradient is used.all FADH2 + NADH -->about 340ATP. (there is always some variation in electron transport chain calculation because sertain quantity of gradient difference doesent always create certain amount of atp) total = 36-38 ATP From the complete oxidation of one glucose molecule to carbon dioxide and oxidation of all the reduced coenzymes. x 10 = 360-380 ATP ---final anwer checkt from wiki also, about the same, should be correct----
