During which process is most ATP generated in the cell?

Question

Quizplus · Accepted Answer

The majority of ATP is generated during electron transport coupled with chemiosmosis, where the electron carriers (such as NADH and FADH2) transfer electrons down the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. This proton gradient is used by ATP synthase to generate ATP through oxidative phosphorylation. Glycolysis only yields a net of two ATP molecules and pyruvate oxidation yields two more ATP molecules, while the citric acid cycle yields a net of two ATP molecules. Fermentation does not utilize the electron transport chain and therefore does not generate ATP through chemiosmosis.
