Question
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen, the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
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 cells to make small amounts of ATP in the absence of oxygen.

As the cells run out of oxygen, they switch to anaerobic respiration, which allows the cells to make small amounts of ATP in the absence of oxygen.
During intense exercise, such as weightlifting, muscle cells may not receive enough oxygen to meet their energy demands. In this scenario, the cells will resort to anaerobic respiration (specifically lactic acid fermentation) to produce ATP. This process allows them to generate energy without oxygen, but it is significantly less efficient than aerobic respiration and leads to the accumulation of lactic acid, which contributes to muscle fatigue.
