Aerobic respiration of one glucose molecule yields about
A38 ATP molecules
B2 ATP molecules only
C12 ATP molecules in total
D50 ATP molecules in total
Answer & Solution
Correct answer: A. 38 ATP molecules
1. The chapter states one mole of glucose gives 38 molecules of ATP on full oxidation.
2. Anaerobic respiration gives only 2 ATP.
3. The aerobic figure is much higher because oxygen completes the breakdown.
4. So option A is correct.
