WebChemiosmosis occurs in Mitochondria as well as in chloroplasts and also in several bacteria and archaebacteria. This is an ATP generating process which happens as a … WebChemiosmosis generates 90 percent of the ATP made during glucose catabolism and is also the method used in the light reactions of photosynthesis to harness the energy of sunlight. The production of ATP using the process of chemiosmosis is called oxidative phosphorylation because of the involvement of oxygen in the process. WebThis flow of hydrogen ions across the membrane, called chemiosmosis, must occur through a channel in the membrane via a membrane-bound enzyme complex called ATP synthase ( Figure 8.15 ). The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened. margherita ciampi radioestesia evolutiva

Chemiosmosis Definition and Examples - Biology …

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… WebMore broadly, chemiosmosis can refer to any process in which energy stored in a proton gradient is used to do work.
