Question

d) Why do muscles switch from aerobic respiration to anaerobic respiration ?​

Answer 1

Anaerobic ATP Production

Anaerobic ATP ProductionWhen muscles are contracting very quickly, which happens during vigorous exercise, oxygen cannot travel to the muscle cells fast enough to keep up with the muscles' need for ATP. At this point, muscle fibers can switch to a breakdown process that does not require oxygen.

You need to transfer energy from glucose to your muscles very quickly. However your body cannot get oxygen to its muscles quickly enough for aerobic respiration to occur.

This is why anaerobic respiration happens instead.
