WebBiochemically-purified preparations of PSI reaction centers contain about 100 molecules of chlorophyll a. The reaction center chlorophyll in this photosystem, called P700 after the wavelength where absorption of a photon causes bleaching of absorbance, was proposed to be a dimer of chlorophylls based on the optical properties of synthetic ... WebThe reaction center pigments of PS II are called P680, which are able to absorb light with the wavelength of 680 nm (Figure. 4). In addition, The PS I core complex consists of reaction center pigments P700, of which the maximum absorption wavelength is 700 nm. bing maps uk directions manchester
