Detailed Solution

Chemiosmosis requires a membrane, a proton pump, a proton gradient and ATP synthase.

The ATP synthase enzyme consists of two parts: one called the CF₀ is embedded in the thylakoid membrane and forms a transmembrane channel that carries out facilitated diffusion of protons across the membrane. The other portion is called CF1 and protrudes on the outer surface of the thylakoid membrane on the side that faces the stroma. The break down of the gradient provides enough energy to cause a conformational change in the CF1 particle of the ATP synthase, which makes the enzyme synthesise several molecules of energypacked ATP.
