WebPsaA is a core protein of photosystem I. In plants and cyanobacteria, the primary step in oxygenic photosynthesis, the light induced charge separation, is driven bytwo large membrane intrinsic protein complexes, the photosystems I and II. Synonym: Photosystem I P700 chlorophyll a apoprotein A1. immunogen WebIn photosystem II (P680), the e- comes from the splitting of water, which releases oxygen as a waste product. In photosystem I (P700), the e- comes from photosystem II via the ETC. There are two parts of the ETC in the light reaction: The first, transports e- from PSII to PSI and generates a H+ gradient. The second transports e- from PSI to ...
