- Chemiosmosis is a process involved in ATP synthesis.

- During this process, protons in the Strom decrease in number, while in the lumen there is an accumulation of protons. This creates a proton gradient across the thylakoid membrane, and no formation of an electron gradient occurs.

The breakdown of this proton gradient leads to the synthesis of ATP.

Hence the correct option is (a)
