WebSo, remember, that even though it's kind of funky that we're talking about kind of two and a half ATP per molecule of NADH or per molecule of FADH two, really, what this is alluding to is the role of this chemi-osmotic coupling, or using the proton gradient to fuel to ATP synthase and because we're talking about protons now, we need to factor ... 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.
