a weightlifter is using heavy weights in short bursts for a competition. becuase his muscle cells are not able to take in enough oxygen to make very much atp the weightlifter begins to get fatigue in his myscle. which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

as the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of atp in the absence of oxygen.

as the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.

the cells will never run out of oxygen if the weightlifter is breathing.

as the cells run out of oxygen, they will continue to make the same amount of atp, since oxygen is not required to make atp.

As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen; when the weightlifter’s muscle cells are not able to take in enough oxygen to make very much ATP, as he competes in the event.

Explanation:

Anaerobic respiration takes place when there is too low or no oxygen to perform aerobic respiration. This transfers the energy to the cells from glucose. It produces energy very quickly along with lactic acid and other waste products.

Anaerobic respiration is highly useful when short bursts of energy are required very quickly to energize the muscles to perform high intensity activities like wrestling, weightlifting, intense short workouts, etc.

Lactic acid fermentation causes the muscles to burn out when high intense short burst physical activities are performed.
