Definition of Oxidative Phosphorylation: Oxidative phosphorylation is the process by which energy from electron transport chain (respiratory chain) is used to make ATP, and is the culmination of energy yielding metabolism in aerobic organisms. Answer: B. Cellular respiration introduction. Production of … In animals, oxygen enters the body through the respiratory system. The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized NADH and FADH 2. Oxidative phosphorylation refers to a type of phosphorylation that uses the energy released from the electron transport chain to generate ATP. Coenzyme Q is involved in electron transport as. O2 + 4H+ + 4e– = 2 H2O The large amounts of energy released during the process are simultaneously used as a proton gradient to synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and phosphate.
