Which activity best takes place during exercise? A cell respiration increases B cell respiration decreases C oxygen production increases D carbon dioxide production decreases

A.

Explanation:

Exercise, during exercise, the oxygen in muscle converts available glucose into energy and heat which increases cell respiration. Exercise increases cellular respiration mainly in muscle cells and further prolonged exercise increase the number of mitochondria in muscle cells and it causes further increase the rate of cellular respiration. There is the increase of carbon dioxide production during exercise.
