WebSep 4, 2024 · Oxidative phosphorylation. Oxidative phosphorylation is the final stage of aerobic cellular respiration. There are two substages of oxidative phosphorylation, Electron transport chain and Chemiosmosis. In these stages, energy from NADH and FADH 2, which result from the previous stages of cellular respiration, is used to create ATP. WebOct 8, 2024 · Phosphorylation is the process through which a phosphate group is transferred from one molecule to a protein, usually within a biological system.
