Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. It refers to the process of moving ions to the other side of a biological membrane which will generate an electrochemical gradient. Chemiosmosis is the process of a molecule moving from high to a low concentration based on its charge and concentration inside a cell. ATP synthase is the enzyme that makes ATP in chemiosmosis. 36 molecules of ATP can be produced for each glucose molecule during cellular respiration in Krebs cycle, electron transport and chemiosomosis. The other 2 ATP molecules are produced through glycolysis. So the net yield is 38 molecules of ATP.
