WebAug 28, 2024 · Chemiosmosis occurs in the cell membrane of prokaryotes such as bacteria and archaea, which lack mitochondria and chloroplasts. When a proton gradient occurs on the other side of the membrane, hydrogen ions (protons) travel across the cellular membrane via ATP synthase (a transport protein). Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H ) across a membrane during cellular respiration or photosynthesis. Hydrogen ions, or protons, will diffuse from a region of high proton concentratio…
