What process is described here? A concentration gradient of H+ ions is created in the periplasmic space by actively transporting the ions across the membrane using the energy liberated when carrier molecules are oxidized. When the H+ ions pass through ATPase, enough energy is generated to add phosphate groups onto ADP molecules.

Question

Quizplus · Accepted Answer

The process described is oxidative phosphorylation, which involves the creation of a proton gradient across a membrane and the generation of ATP as protons flow back across the membrane through ATP synthase. This is a key part of cellular respiration, occurring in the mitochondria of eukaryotic cells and the plasma membrane of prokaryotic cells.
