In the light reaction of photosynthesis, if you treat the thylakoid membrane with a chemical that dissipates proton gradient, what will happen to the ATP production?
In the light reaction of photosynthesis, if you treat the thylakoid membrane with a chemical that dissipates proton gradient, there will be no ATP production. Proton gradient is responsible for ATP production during light reaction of photosynthesis. The chlorophyll obtains its electrons from water by producing oxygen. During the electron transport process H+ is pumped across the thylakoid membrane, and causing electrochemical proton gradient that drives the synthesis of ATP in the stroma.
