Question

Which process takes place in muscle cells when they do not get enough oxygen? electron transport chain cellular respiration ethyl alcohol fermentation lactic acid fermentation

Answer 1

lactic acid fermentation

Step-by-step explanation:

Muscle derive energy in form of ATP by aerobic cellular respiration for their contraction. However, continuous physical activities deprive the muscles of oxygen. The process of lactic acid fermentation does not require the presence of oxygen to occur.

Therefore, in the absence of oxygen, lactic acid fermentation occurs in muscles to serve as a quick source of ATPs for muscle contraction.
