Explanation:
Detailed explanation-1: -Cellular respiration (see chemical reaction below) is a chemical reaction that occurs in your cells to create energy; when you are exercising your muscle cells are creating ATP to contract. Cellular respiration requires oxygen (which is breathed in) and creates carbon dioxide (which is breathed out).
Detailed explanation-2: -What is aerobic exercise? Aerobic exercise provides cardiovascular conditioning. The term aerobic actually means “with oxygen, ‘’ which means that breathing controls the amount of oxygen that can make it to the muscles to help them burn fuel and move.
