Abstract
Light-driven electron transport is coupled to ATP synthesis in chloroplasts. While the nature of the coupling and the structures of key components are now known, there has long been disagreement over pathways of electron transport. Recent results now put an old idea back on the agenda-cyclic electron transport around photosystem I.
