A
membrane-bound complex in plants and photosynthetic bacteria,
responsible for light-harvesting and primary
electron transfer.
Comprises light-harvesting pigments such as chlorophyll; a primary
electron-transfer centre, and secondary electron carriers. In green
plant
photosynthesis, Photosystem I transfers electrons from
plastocyanin to a [2Fe-2S]
ferredoxin, and contains
iron-sulfur proteins. Photosystem II transfers electrons from the oxygen-evolving
complex to plastoquinone, and contains an iron centre.
