Chemiosmosis - Wikipedia
https://en.wikipedia.org/wiki/Chemiosmosis
WebChemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H +) across a membrane during cellular respiration or photosynthesis.

WebChemiosmosis is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation. It is also the method used in the light reactions of photosynthesis to harness the energy of sunlight in the process of photophosphorylation.

WebAbout. Transcript. Oxidative phosphorylation is a vital cellular respiration process that generates ATP. It involves the oxidation of NADH and FADH2 and phosphorylation. The process creates a hydrogen gradient, enabling chemiosmosis and ATP synthesis. This energy conversion is essential for all life forms, from bacteria to sharks.

WebOxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient.
