Cartoon Schematic of Electron Flow in Chloroplasts

Caption

A cartoon schematic of electron transport chain of photosynthesis in which energy from sunlight creates high-energy electrons that are shuttle among various protein complexes. The electron shuttling process is coupled with proton pumps that power ATP formation by ATP synthase. An electron can flow linearly to power NADPH formation or it can be cycled between photosystem I and NDH to boost ATP synthesis.
