a weightlifter is using heavy weights in short bursts for a competition because his muscle cells are not able to take in enough oxygen to make very much ATP 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 most likely process going on in the muscles of the weightlifter as he competes in his event is anaerobic glycolysis. Anaerobic glycolysis is a metabolic process that occurs in muscle cells when there is not enough oxygen available to meet the energy demands of the exercise. It involves the breakdown of glucose to produce ATP without the requirement of oxygen. This process is less efficient than aerobic respiration but can quickly generate ATP for short bursts of high-intensity exercise, such as weightlifting. The accumulation of lactic acid during anaerobic glycolysis contributes to muscle fatigue.
