WebThe gradient is usually used to drive ATP synthase, flagellar rotation, or metabolite transport. [15] This section will focus on three processes that help establish proton gradients in their respective cells: … 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. bilz usa tool holder

WebAnd ATP synthase provides a channel for those protons. But as those protons travel through the ATP synthase, they turn this part of it, which drives this axle, and then this axle nudges these parts of the protein so that they jam together an ADP with a phosphate group to produce ATP. WebATP synthesis is driven by an inverse flow of protons along the gradient. Mitchell’s proposal was called “ chemiosmotic theory “. It won him the Nobel Prize in 1978. This gradient between stroma and lumen can be maintained because the thylakoid membrane is generally impermeable to protons.
