Which of the following produces the most ATP when glucose (C6H12O6) is completely oxidized to carbon dioxide and water?
A) glycolysis
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 mitochondria and utilizes the electron transport chain to generate a proton gradient, which drives ATP synthesis through ATP synthase. The other options listed also contribute to ATP production, but oxidative phosphorylation produces the most ATP.
