Answer:
Diffusion forces protons to travel through ATP synthase because the membrane is not permeable to protons
Explanation:
ATP synthase is the enzyme that allow the production of ATP from adenosine diphosphate. The ATP synthase allows is the protein found in the cell membrane, which allow protons to pass through the membrane.
The concentration gradient can be compared to diffusion of water where particles move from region of higher concentration to lower concentration through a permeable membrane
In this case, the concentration gradient will force the proton through the membrane , so that, the free energy can be used by ADP to produce ATP.
