Question
Which process in photosynthesis is directly responsible for ATP synthesis?
Correct Answer
Option C is the correct answer.
Detailed Explanation
ATP is synthesized during the light-dependent reactions via chemiosmosis. A proton gradient built up across the thylakoid membrane drives protons through ATP synthase, phosphorylating ADP to ATP.
Hint
This is the same fundamental mechanism used in cellular respiration.
