Question

Why is aerobic respiration more beneficial than anaerobic respiration?

Answer 1

Much less energy is released during anaerobic respiration than during aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces oxygen debt. 

Answer 2

Aerobic respiration is the respiratory pathway of choice for oxygen-dependent organisms because of its greater efficient.

Aerobic respiration is more beneficial than anaerobic respiration because aerobic respiration provides more ATP molecules. During aerobic respiration one molecule of glucose can be converted into up to 32 molecules of ATP while during anaerobic respiration only two molecules of ATP per glucose molecule are gained .

And for muscle to undergo repeated contraction , it requires more ATP . so aerobic respiration is more efficient.
