WebThe pigment that is mainly involved in trapping light energy is chlorophyll. Thus, it is called a pigment system or photosystem. While the pigment system 1 comprises chlorophyll A-695, chlorophyll A-670, chlorophyll A-680, chlorophyll A-700, chlorophyll B, and carotenoids, pigment system 2, on the other hand, comprises chlorophyll A-670 ... Two main subunits of PSI, PsaA and PsaB, are closely related proteins involved in the binding of the vital electron transfer cofactors P700, Acc, A0, A1, and Fx. PsaA and PsaB are both integral membrane proteins of 730 to 750 amino acids that contain 11 transmembrane segments. A [4Fe-4S] iron-sulfur cluster called Fx is coordinated by four cysteines; two cysteines are provided each by PsaA and PsaB. The two cysteines in each are proximal and located in a loop between the ninth … WebMay 14, 2024 · How the System Works Figure \(\PageIndex{1}\): Photosystems.
