Question

1. anaerobic respiration. a. construct an explanation for why humans breathe more heavily during exercise. your answer should include the role of oxygen and energy production. 1

Explanation:

During heavy - exercise, humans breathe more heavily because oxygen is crucial for cellular respiration which produces energy. Oxygen is used in aerobic respiration to break down glucose and release energy in the form of ATP. As the body's energy demand increases during heavy exercise, more oxygen is needed to meet this demand, so the breathing rate increases.

Answer:

During heavy exercise, the body's energy demand rises. Oxygen is essential for aerobic respiration to produce energy (ATP) from glucose. To supply the required oxygen for increased energy production, humans breathe more heavily.
