Happily coupled : Photosystem II and photosystem I can be coupled in a sol–gel system so that electron flow can be directly mediated from photooxidized water at the donor side of photosystem II to the highly reducing acceptor side of photosystem I. The electron transfer pathway is set up by addition of the amphipathic quinone analogue 2,6dichlorophenolindophenol (DCPIP) to the sol–gel mixture to provide a pool of redox carriers (see picture).
