The structure responsible for O2 creation transfers electrons from water. More detail...		The second complex in the chain pumps protons as it transfers electrons. More detail...		Here electrons are re-energized and transported to FNR to produce NADPH. More detail...		This complex uses the proton gradient maintained by the photosynthetic ETC to synthesize ATP. More detail...
