Final answer:
NADH is produced from each reaction described except during anaerobic glycolysis.
Step-by-step explanation:
NADH is produced from each reaction described except during anaerobic glycolysis. During aerobic glycolysis, pyruvate is converted to acetyl CoA, which enters the citric acid cycle. In the citric acid cycle, NADH and FADH2 are produced. However, during anaerobic glycolysis, pyruvate is converted to lactate or ethanol, and NADH is not produced.
