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. WebMar 6, 2024 · In the mitochondrion, what the proton gradient does is facilitate the production of ATP from ADP and Pi.
