Final answer:

Aerobic respiration primarily produces ATP for muscles, while anaerobic respiration supplements energy needs during oxygen scarcity or high-intensity activities.


Explanation:

Aerobic respiration is the primary process that produces ATP for muscles, and anaerobic respiration provides extra ATP if aerobic respiration cannot meet the muscles' demand for energy.

During light exercise, aerobic respiration occurs in the mitochondria of muscle fibers, generating ATP efficiently with the presence of oxygen. On the other hand, anaerobic respiration, specifically lactic acid fermentation, steps in to produce additional ATP quickly when oxygen levels are low or during intense activities.

Although aerobic respiration yields significantly more ATP per glucose molecule than anaerobic respiration, both processes play vital roles in providing energy to muscle cells based on different energy demands.
