WebThe protein gradient drives ATP synthase activity, which generates ATP. Oxidative Phosphorylation is the fourth and final step in cellular respiration and is the main … 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.

WebATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ... WebUsually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the energy that cells need to do work. When they do not get enough oxygen, the cells use anaerobic respiration, which does not use oxygen.
