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 can slow or halt aerobic respiration, forcing cells to switch to less - efficient anaerobic respiration, producing lactic acid.

Answer:

A person holding their breath too long would reduce oxygen supply to cells. This would slow or stop aerobic cellular respiration. Cells may then switch to anaerobic respiration, which is less efficient and can lead to lactic acid buildup.
