= Photosystem
An organized light-harvesting and reaction-center assembly supporting photosynthetic <energy> conversion.
An antenna transfers excitation to a reaction centre, where charge separation initiates <electron> transfer. This distinguishes capture of a <photon> from conservation of its <energy> in a redox reaction. In <oxygenic photosynthesis>, two <photosystems> act in a connected electron-transfer chain. <Molecular Biology of the Cell, 4th edition by Bruce Alberts and others>[Chapters 3, 6 and 15, protein function, translation and cell signalling]{ref}
