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. Anaerobic respiration may start as a result. This leads to lactic - acid accumulation and fatigue.

Answer:

Oxygen supply to cells is reduced. Aerobic respiration is inhibited and anaerobic respiration may increase, leading to lactic - acid build - up and discomfort.
