alleryDuring chloroplast ATP synthesis, H+ flows through ATP synthase from:
AStroma to cytoplasm
BStroma to thylakoid lumen
CThylakoid lumen to stroma
DCytoplasm to chloroplast envelope
Answer & Solution
Correct answer: C. Thylakoid lumen to stroma
Light-driven processes accumulate H+ in the thylakoid lumen. Return of H+ to the stroma through ATP synthase powers ATP formation.
