Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-2: -This process is called cellular respiration. During cellular respiration, the cell uses oxygen to break down sugar. Breaking down sugar produces the energy our body needs.

Detailed explanation-3: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.

Detailed explanation-4: -A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, aerobic respiration, and oxidative metabolism.

Detailed explanation-5: -Cellular respiration can be defined generally as the process by which chemical energy is released during the oxidation of organic molecules. If it requires oxygen it is called aerobic respiration, whereas if it takes place in the absence of oxygen it is anaerobic respiration.
