Question

athletes sometimes train at high altitudes where there is less oxygen. how might this affect their cellular respiration and performance? your answer

Explanation:

At high - altitudes, low oxygen levels can shift cellular respiration from aerobic to anaerobic. Anaerobic respiration produces less ATP per glucose molecule and lactic acid as a by - product, which can cause muscle fatigue. However, the body may adapt over time by increasing red blood cell production to carry more oxygen, potentially improving performance once back at lower altitudes.

Answer:

At first, cellular respiration may shift to less efficient anaerobic mode, causing fatigue. But over time, the body may adapt by increasing red - blood cell production which can enhance performance later.
