WebDec 21, 2006 · Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration. WebATP synthase is a complex, molecular machine that uses a proton (H +) gradient to form ATP from ADP and inorganic phosphate (Pi). (Credit: modification of work by Klaus Hoffmeier) Dinitrophenol (DNP) is an uncoupler that makes the inner mitochondrial membrane leaky to protons. It was used until 1938 as a weight-loss drug.

WebDiffusion does not require energy because the molecules move down their concentration gradient (from areas of high to low concentration). Proton pumps use energy from ATP to create electrochemical gradients, with a high concentration of protons on one side of a plasma membrane. This electrochemical gradient can then be used as a source of ... WebProton pumps just like any mechanochemical process generates heat, normally much of this heat is reclaimed in the production of ATP. Without thermogenin proton pumps produce a proton gradient, the gradient is used to power atp synthase. thermogenin is a channel protein that creates holes in the membrane preventing a gradient from building up. phineas and ferb love muffin members
