Question

how would cellular respiration be affected if a person holds their breath too long? your answer

Explanation:

Cellular respiration requires oxygen. Holding breath reduces oxygen intake. This leads to decreased aerobic respiration and increased anaerobic respiration to produce energy. Lactic - acid may accumulate due to anaerobic respiration in muscles.

Answer:

Oxygen supply to cells is reduced, aerobic respiration decreases, anaerobic respiration increases, and lactic - acid may accumulate in muscles.
