Breathing faster when we exercise is necessary to expel ________.

Question

Quizplus · Accepted Answer

Breathing faster during exercise is necessary to expel carbon dioxide, which is a waste product of cellular respiration, and to bring in more oxygen to support aerobic metabolism. This helps to maintain proper pH levels and deliver sufficient oxygen to working muscles. Anaerobic metabolism does not rely on oxygen and therefore would not require an increase in oxygen intake during exercise.
