Question

Quizplus · Accepted Answer

During ATP synthesis in the chloroplast F₁F_o ATP synthase, the direction of the proton current is from the thylakoid lumen to the stroma. This flow of protons drives the rotation of the ATP synthase complex, which ultimately leads to the formation of ATP from ADP and Pi.
