Chemiosmosis is the movement of ions across a semipermeable membrane, down their electrochemical gradient. An example of this would be the generation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis.
An ion gradient has potential energy and can be used to power chemical reactions when the ions pass through a channel (red).
Hydrogen ions, or protons, will diffuse from an area of high proton concentration to an area of lower proton concentration, and an electrochemical concentration gradient of protons across a membrane can be harnessed to make ATP. This process is related to osmosis, the diffusion of water across a membrane, which is why it is called "chemiosmosis".
ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows protons to pass through the membrane and uses the free energy difference to phosphorylate adenosine diphosphate (ADP), making ATP. The generation of ATP by chemiosmosis occurs in mitochondria and chloroplasts, as well as in most bacteria and archaea, an electron transport chain pumps H+ ions in the thylakoid spaces through thylakoid membranes. The energy from the electron movement through electron transport chains cross through ATP synthase which allows the proton to pass through them and use this free energy difference to photophosphorylate ADP making ATP.:-) :-) :-) :-) :-) :-) :-) --

Chemiosmosis Definition
Chemiosmosis is when ions move by diffusion across a semi-permeable membrane, such as the membrane inside mitochondria. Ions are molecules with a net electric charge, such as Na+, Cl–, or specifically in chemiosmosis that generates energy, H+. During chemiosmosis, ions move down an electrochemical gradient, which is a gradient of electrochemical potential (a form of potential energy). Since chemiosmosis is a type of diffusion, ions will move across a membrane from areas of high concentration to areas of low concentration. Ions also move to balance out the electric charge across a membrane. hope this helps!!!!!!!
