B) fermentation
C) oxidation of pyruvate to acetyl CoA
D) citric acid cycle
E) oxidative phosphorylation (chemiosmosis)

Question

Quizplus · Accepted Answer

Oxidative phosphorylation (chemiosmosis) produces the most ATP when glucose is completely oxidized to carbon dioxide and water. This process occurs in the inner membrane of the mitochondria and allows for the production of up to 32-34 ATP molecules, as compared to glycolysis which only produces 2 ATP, fermentation which produces only 2 ATP or less, oxidation of pyruvate to acetyl CoA which only produces 2 ATP, and citric acid cycle which produces only 2 ATP.
