Explanation:
Detailed explanation-1: -Aerobic Glycolysis This pathway requires oxygen to produce ATP, because carbohydrates and fats are only burned in the presence of oxygen. This pathway occurs in the mitochondria of the cell and is used for activities requiring sustained energy production.
Detailed explanation-2: -Muscles performing work require increasing amounts of energy as the workload increases, which correspondingly requires more and more oxygen. We breathe more when we exercise to help remove the large amount of carbon dioxide (CO2) that is produced by the working muscles.
