The generation of ATP by the movement of hydrogen ions down their concentration gradient across a membrane occurs because of a process called a.
chemiosmosis

b.
diffusion

c.
reverse osmosis

d.
passive transport

Hmm h hmmm hm reverse osmosis??

A. chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An example of this would be the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis.

Nine months old i think but i’m not that sure
