During intense exercise, the muscle cells require constant supply of ATPs but the supply of oxygen is low. In that case - the mu
larisa [96]

Answer:

Aerobic to lactic acid fermentation pathway

Explanation:

ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.

Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.
