Question

What happens to protons (H⁺) during ATP synthesis in photosynthesis?

Options

Choose one · Correct answer highlighted

They are pumped into the stroma They move from the stroma to the lumen They pass through ATP synthase into the stroma Correct They are used to reduce NADP⁺

Explanation

Protons move through ATP synthase from the lumen to the stroma, generating ATP through chemiosmosis. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.
