Question

multiple choice question
in aerobic respiration, how many nadh molecules are produced for each glucose molecule?

○ 2

○ 10

○ 32

○ 5

Explanation:

Step1: Recall aerobic respiration stages

Aerobic respiration has glycolysis, pyruvate oxidation, and the citric acid cycle (Krebs cycle), plus oxidative phosphorylation. In glycolysis, 2 NADH are produced per glucose. Pyruvate oxidation: 2 pyruvates → 2 acetyl - CoA, producing 2 NADH. Citric acid cycle: 2 acetyl - CoA enter, each cycle produces 3 NADH, so 2×3 = 6 NADH.

Step2: Sum NADH production

Total NADH: Glycolysis (2) + Pyruvate oxidation (2) + Citric acid cycle (6) = 10.

Answer:

10 (the option with "10")
