WebThree major protein complexes are involved in running the "Z" scheme: (1) Photosystem II; (2) Cytochrome bf complex (containing Cytb 6 ; FeS; and Cytf ) and (3) Photosystem I. The diagram does not show where and how ATP is made. For a description of how the Z Scheme operates, click here. WebEach photosystem consists of a light-harvesting complex and a core complex. Each core complex contains a reaction centre with the pigment (either P 700 or P 680) that can be photochemically oxidized, together with electron acceptors and electron donors. In addition, the core complex has some 40 to 60 chlorophyll molecules bound to proteins. lexas suv used 2012 2013 at bmw south atl ga lexa speaker
