Atp synthesis in chloroplasts is very similar to that in mitochondria: electron transport is coupled to the formation of a proton (h ) gradient across a membrane. the energy in this proton gradient is then used to power atp synthesis. two types of processes that contribute to the formation of the proton gradient are:

a. processes that release H+ from compounds that contain hydrogen, and

b. processes that transport H+ across the thylakoid membrane.

Explanation:

ATP synthesis can be defined as the process where ATP is produced from the transfer of electrons from membrane to the matrix of the cells. When ATP is synthesized, it is used as a source of energy in the at organism.

ATP is synthesized in plants using the enzyme ATP synthase that is found in the chloroplasts during the process of photosynthesis.

Electron transport is joined to the formation of a proton (h ) gradient by processes that release H+ from compounds that contain hydrogen, and processes that transport H+ across the thylakoid membrane across the membrane. The energy present in this proton gradient is then used to start up the process of synthesizing ATP.

this is a good question! i'll do some research and come back when i have the answer!
