In cellular respiration, most ATP molecules are produced by oxidative phosphorylation.
Cellular respiration is the process by which organisms combine oxygen and food molecules, direct the chemical energy of those substances to life-sustaining activities, and dispose of carbon dioxide and water as waste.
Cell respiration is the process that occurs in the mitochondria of living organisms (animals and plants), breaking down sugar in the presence of oxygen and releasing energy in the form of ATP. In this process, carbon dioxide and water are released as waste.
Oxidative phosphorylation is the process by which ATP synthesis is linked to electron transfer and associated oxygen consumption through the mitochondrial electron transport chain.
