which of the following statements about photosystem ii are correct? it is a multimolecular transmembrane assembly containing several polypeptides, several chlorophyll molecules, a special chlorophyll (p680), pheophytin, and plastoquinones. it transfers electrons to photosystem i via the cytochrome bf complex. it uses light energy to create a separation of charge, the potential energy of which can be used to oxidize h2o and to produce a reductant, plastoquinol. it uses an fe2 -cu center as a charge accumulator to form o2 without gener- ating potentially harmful hydroxyl radicals, superoxide anions, or h2o2.
