WebMay 18, 2024 · The turning of parts of this molecular machine facilitates the addition of a phosphate to ADP, forming ATP, using the potential energy of the hydrogen ion gradient. Figure 8.6. 2: ATP synthase is a complex, molecular machine that uses a proton (H+) gradient to form ATP from ADP and inorganic phosphate (Pi). 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.
