Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred b… WebPhotosystem I (PS I): This photosystem has chlorophyll a molecule in its reaction center that absorbs maximum light of 700 nm wavelength. Therefore, it is also called P700. Photosystem II (PS II): Its reaction center has chlorophyll a molecule that absorbs maximum light of 680 nm wavelength. Thus, it is called P680. shuttle tickets glacier park
