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 … WebSolution. The correct option is B. Pheophytin. Pheophytin is the primary electron acceptor for PS II. It picks up the electron given out by P 680 and passes it to the next electron acceptor plastoquinone, which further passes it to …
Electron acceptors of photosystem 2 in the cyanobacterium
WebJul 4, 2024 · It is a primary electron acceptor and contains chlorophyll with the Magnesium replaced by two protons5. Then the electron is transferred to Plastoquinone (PQ) at QA site then QB site4. Plastoquinone can be one or two electron acceptor or donor from … WebThe special pair of each photosystem passes electrons to a different primary acceptor.

Cyclic Photophosphorylation & Noncyclic Photophosphorylation
WebApr 12, 2024 · The primary function of the photosystem I is in NADPH synthesis, where it receives the electrons from PS II. The primary function of the photosystem II is in the hydrolysis of water and ATP synthesis. Core Composition. The PSI is made up of two subunits which are psaA and psaB. The PS II is made up of two subunits made up of D1 … WebAug 8, 1983 · The electron acceptors iron-quinone signal in detergent preparations of of photosystem 2 seem to be similar to those in C. reinhardtii PS2 [4] indicated a pH … WebElectrons are transferred from the PS II and then passed on to the pigments of PS I. Then, electrons get excited and transferred to another acceptor. These electrons are then moved downhill again to a molecule of N A D P +. The addition of these electrons results in formation of N A D P H. The electron released from PS II by P 6 8 0 must be ... money go round
