Describe how a low-energy electron in water becomes a high-energy electron on the primary acceptor of a reaction centre. Ku 2. Sketch the linear electron transport chain that ends with the passing of final electrons to NADP+ to create NADPH. Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to …
WebAlthough photochemically active reaction centres, primary chlorophyll antennae of both PS1 an PS2 and excitation energy transfer between the chlorophyll antennae complexes of PS1 and PS2 are evident at early stages of development, it is not known whether electron transfer occurs from water to a terminal electron acceptor via PS2 to PS1 with a … WebCommunity Answer.
