Cellular Respiration

Cellular Respiration Definition Cellular respiration is a metabolic process consisting of a series of steps to convert chemical energy (sugar) into a usable form of energy (ATP) in the cell. The reactions involved in cellular respiration are catabolic reactions that involve the breakdown of larger organic molecules into smaller forms. The overall process of cellular respiration takes place in a …

Oxidative Phosphorylation

Oxidative Phosphorylation and ETC

The NADH and FADH2, formed during glycolysis, β-oxidation of fatty acids and the TCA cycle, give up their electrons to reduce molecular O2 to H2O. Electron transfer occurs through a series of protein electron carriers, the final acceptor being O2; the pathway called as the electron transport chain (ETC). The function of ETC is to facilitate the controlled release of …
