Question

what process produces most of the nadh that contributes to atp synthesis in the cell? multiple choice glycolysis the citric acid cycle anaerobic fermentation the mitochondrial proton pumps the electron transfer from fadh₂

Explanation:

Glycolysis produces 2 NADH per glucose. Anaerobic fermentation does not produce new NADH for ATP - synthesis in the long - run. Mitochondrial proton pumps use NADH for ATP synthesis but don't produce it. Electron transfer from FADH₂ is not a NADH - producing process. The citric acid cycle produces 3 NADH per acetyl - CoA entering the cycle, and since each glucose produces 2 acetyl - CoA, it contributes a large amount of NADH for ATP synthesis.

Answer:

The citric acid cycle
