- 7.5.2: Chemiosmosis and Oxidative Phosphorylation
Chemiosmosis (or chemiosmosis coupling) is the diffusion of ions through a semipermeable membrane, like osmosis, from greater ion concentration into less ion concentration until the internal and external concentrations are equal.
3 Φεβ 2023 · Chemiosmosis is the process by which hydrogen ions (protons) diffuse to the other side of the biological membrane from high to low concentration. It creates a difference in their concentration (electrochemical gradient) between the two sides of the semi-permeable membrane.

Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.
4 Σεπ 2023 · 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.
16 Δεκ 2021 · During chemiosmosis, electron carriers like NADH and FADH donate electrons to the electron transport chain. The electrons cause conformation changes in the shapes of the proteins to pump H+ across a selectively permeable cell membrane.
