WebChemiosmosis is the movement of ions down an electrochemical gradient through a semipermeable membrane. For instance, hydrogen ions (H+) move across a membrane during photosynthesis or in cellular respiration to form adenosine triphosphate (ATP). In a channel (red), the ions can pass through an ion gradient that has potential energy.
