Question

What is the fate of protons (H+) accumulated in the thylakoid lumen?
Options
A Used in the Calvin cycle
B Flow through ATP synthase to drive ATP production
Correct Answer
C Released as oxygen
D Converted to glucose
Correct Answer

Option B is the correct answer.

Detailed Explanation

The proton gradient (higher concentration in the lumen than in the stroma) represents potential energy. Protons flow back into the stroma through the ATP synthase channel, and this flow drives the phosphorylation of ADP to ATP.

Hint

They are the driving force for ATP synthesis.
