Question

Muscular cell shrinks if oxygen is not supplied why?

Answer 1

Muscle can no longer use oxygen to generate ATP and turn to anaerobic glycolysis, a process that breaks down sugar without oxygen, to generate ATP from glycogen, a sugar stored inmuscle. The breakdown of glycogen produces enough energy to contract the muscles, and also produces lactic acid.

Answer 2

Due to lack of oxygen lactic acid and co2 is produced in our body so our muscular cell shrink.
