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. WebHill Reaction H2O+ Aox --> AH2(red) + O2 Aox= Hill reagent (NADP) -Water (not CO2) serves as the source of electrons. NADP+ serves as the final electron acceptor which is …
