WebJun 7, 2024 · Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include: 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.
