Web: relating to or being a hypothesis that seeks to explain the mechanism of ATP formation in oxidative phosphorylation by mitochondria and chloroplasts without recourse to the formation of high-energy intermediates by postulating the formation of an energy gradient of hydrogen ions across the organelle membranes that results in the reversible … WebJan 3, 2024 · All cells use an electron transport chain (ETC) to oxidize substrates in exergonic reactions. The electron flow from reduced substrates through an ETC is like the movement of electrons between the poles of a battery. In the case of the battery, the electron flow releases free energy to power a motor, light, cell phone, etc.
We can define phosphorylation as a biochemical process in which a phosphate molecule is added to some organic compound, such as glucose and adenosine diphosphate (ADP). In the latter example, the addition of phosphate group converts ADP to adenosine triphosphate (ATP), which is a very important … See more The question here arises is what is the purpose of phosphorylation?
