WebWhen light is absorbed by one of the pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level (forming P680*). The high-energy electron is passed to an acceptor molecule and replaced with an electron from water.
Web6.4.6 Other electron donors and acceptors. The non-physiological electron acceptor ferricyanide allows the Hill reaction, a light-dependent oxygen evolution in the absence of NADP+, to be observed. The Em,7 of the Fe (CN) 6 4 − / Fe (CN) 6 3 − couple, +420 mV, is sufficiently positive to accept electrons from reduced plastocyanin, but ...
