Question

Quizplus · Accepted Answer

A proton gradient is created by the difference in pH in the thylakoid membrane. The basic solution outside the thylakoid has a higher pH than the inside, which creates a proton motive force across the membrane. This proton gradient is utilized by ATP synthase to synthesize ATP. Thus, even in a basic solution, ATP can still be synthesized in the thylakoid.
