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. WebAfter that, the proton gradient provides energy for the ATP synthase enzyme, which is likewise contained within the membrane. The energy released by the transport of protons back across the membrane by ATP synthase is utilized to make ATP from ADP and inorganic phosphate. This process takes place as the protons flow through ATP synthase.
