WebEnergy 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: WebPrimary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient. Secondary active transport ( cotransport) , on the other hand, uses an electrochemical gradient – generated by active transport – as an energy source to move molecules against their gradient, and thus … WebATP phosphorylates glutamic acid, making it less stable. Ammonia displaces the phosphate group, forming glutamine.
