Problem: Which of the following processes produces the most ATP per molecule of glucoseA) aerobic respiration B) lactic acid fermentation C) anaerobic respiration D) All produce approximately the same amount of ATP per molecule of glucose

FREE Expert Solution

Recall:

Aerobic Respiration: uses O2 as the final electron acceptor

1 mole of glucose forms 30 to 32 ATP

Lactic Fermentation: follows glycolysis in the absence of O2

1 mole of glucose forms 2 ATP (from glycolysis)

Anaerobic Fermentation: uses a different molecule than O2 as the final electron acceptor

1 mole of glucose forms less than 30 to 32 ATP
