Question

level 4 q4 which of the following processes generates the most atp? a. electron transport chain b. pyruvate oxidation c. glycolysis d. fermentation a. electron transport chain b pyruvate oxidation c. glycolysis d. fermentation

Explanation:

• Glycolysis produces a net of 2 ATP.
• Pyruvate oxidation produces no ATP directly (it produces NADH which is used later).
• Fermentation produces 2 ATP (like in lactic acid or alcoholic fermentation).
• The electron transport chain (part of oxidative phosphorylation) produces the most ATP, around 26 - 28 ATP per glucose molecule, as it uses the high - energy electrons from NADH and FADH₂ to create a proton gradient that drives ATP synthesis through ATP synthase.

Answer:

A. Electron transport chain
