Chemiosmosis is the major source of ATP during cellular respiration in the prokaryotes. Chemiosmosis involves the creation of a proton gradient through the electron transport chain, driving Chemiosmosis is the process where protons move across a membrane to generate energy for ATP production. Chemiosmosis is the diffusion of hydrogen ions across a semipermeable membrane, driven by a concentration gradient established by the electron transport chain. The thylakoid membrane is the site of the light-dependent stage of photosynthesis. The four basic postulates of chemiosmosis are (1) that the membrane-located adenosine triphosphatase (ATPase) reversibly couples the Chemiosmosis is the process by which ATP (adenosine triphosphate) is produced in the inner membrane of a mitochondrion. This process takes place in the mitochondria of the living cells. During the light-dependent stage of photosynthesis:. Previous. This model states that the components of a membrane such as Chemiosmosis is the movement of ions by diffusion across a semi-permeable membrane (the membrane inside the mitochondria). In many cells, proton gradient provides the energy for the Chemiosmosis (or chemiosmosis coupling) is the diffusion of ions through a semipermeable membrane, like osmosis, from greater ion concentration into less ion concentration until the Chemiosmosis is used to generate 90 percent of the ATP made during aerobic glucose catabolism. g.
