Detailed explanation-1: -Oxidative phosphorylation has two parts: the electron transport chain (ETC) and chemiosmosis. The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy.

Detailed explanation-2: -The process of oxidative phosphorylation involves understanding fundamental concepts: electronegativity, the sources of reduced NADH and FADH2, and the anatomy of the mitochondrion. Electronegativity is the ability of an elemental atom to attract a bonding pair of electrons.

Detailed explanation-3: -Electron transport and oxidative phosphorylation are critical activities of protein complexes in the inner mitochondrial membrane, which ultimately serve as the major source of cellular energy.
