The efficiency of aerobic metabolism is greater than that of anaerobic metabolism even though much more energy is released in aerobic than in anaerobic metabolism because
A) aerobic metabolism is linked to oxygen, which is a more powerful oxidizing agent than those in anaerobic metabolism
B) aerobic metabolism produces carbon dioxide and water
C) aerobic metabolism traps much more energy in the form of ATP than does anaerobic metabolism
D) anaerobic metabolism produces two- and three-carbon compounds

Question

Quizplus · Accepted Answer

Aerobic metabolism is more efficient than anaerobic metabolism because it captures much more energy in the form of ATP. While anaerobic metabolism generates a small amount of ATP, aerobic processes like the Krebs cycle and oxidative phosphorylation produce a significantly higher yield of ATP from each glucose molecule.
