Two Fe-S compounds designated as B and A are considered as intermediate between X and ferredoxin. 6-Azido-5-decyl-2,3-dimethoxy-p-benzoquinone (6-azido-Q 0 C 10) was found to replace the native plastoquinone at B (the second stable electron acceptor to Photosystem II (PS II)).The 6-azido-Q 10 C 10 would accept electrons from the primary electron-accepting quinone, Q, thus allowing electron transport through PS II to the plastoquinone pool in thylakoids. Plastoquinone can be one or two electron acceptor or donor from Photosystem II to the cytochrome bf complex in mobile intra-thylakoid membrane5.
