Oxidative Phosphorylation


Oxidative phosphorylation is the process by which cells generate energy in the form of adenosine triphosphate (ATP) from the oxidation of nutrients and the reduction of oxygen. It is the final stage of cellular respiration, which involves the breakdown of glucose, fatty acids, and amino acids into carbon dioxide and water. Oxidative phosphorylation occurs in the mitochondria, the organelles that are responsible for producing most of the ATP in eukaryotic cells.
