The resulting P700 with an excited electron is designated as P700*, which is … Webelectron donor, a chlorophyll a (Chl a) dimer called P700. P700 in the lowest electronically excited singlet state do-nates an electron to the primary electron acceptor, a Chl a monomer referred to as A0. The charge separation is stabi-lized by subsequent electron transfer to secondary accep-tors, i.e., the phylloquinone A1 and the three [4Fe-4S]

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. WebP 700 is defined rigorously only as a spectroscopic entity – the pigment that becomes bleached upon photooxidation. With the advent of the crystal structure, we have come to identify it with the pair of chlorophylls (P A and P B) in the crystal structure occupying the analogous position in the purple bacterial reaction center.
