Detailed explanation-1: -oxidative phosphorylation: A metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). chemiosmosis: The movement of ions across a selectively permeable membrane, down their electrochemical gradient.
Detailed explanation-2: -ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows protons to pass through the membrane and uses the free energy difference to phosphorylate adenosine diphosphate (ADP), making ATP.
Detailed explanation-3: -The process of ATP synthesis using ‘free energy’ obtained when electrons are passed to several carriers (ETC) is known as chemiosmosis. The actual point of the synthesis of ATP takes place when electrons pass the inner mitochondrial membrane. Energy is released within this process, resulting in the synthesis of ATP.
Detailed explanation-4: -Chemiosmosis is driven by the flow of electrons down the electron transport chain, a series of protein complexes in the membrane that forms an electron bucket brigade. Each of these protein complexes accepts and passes on electrons down the chain, and pumps a proton across the membrane for each electron it passes on.
Detailed explanation-5: -Chemiosmotic phosphorylation is the third, and final, biological pathway responsible for the production of ATP from an inorganic phosphate and an ADP molecule via oxidative phosphorylation.
