Document Summary
Atp produced by adp and inorganic phosphate. Nadph is produced by reducing (giving an electron) to nadp+atp and nadph are high energy. This is the purpose of light reactions (atp and nadph production) Photosystem = organized group of 250-400 pigments within the thylakoid membrane that acts as a light gathering antenna complex. The reaction centre consists in a complex of proteins and a pair of chlorophyll a molecules. Photosystem ii has a pair of chlorophyll a with peak in light absorption at 680 nanometers (p 680 ) Each p 680 transfers an excited electron to the primary electron to the primary electron acceptor to be passed down the electron transport chain. When p 680 molecules donate electrons to the primary electron acceptor (oxidized) they are replaced by extracting electrons from water = photolysis. Photosystem i has a pair of chlorophyll a with a peak in absorption at 700 nm (p 700 )
