Electron Paramagnetic Resonance Studies of Zinc-Substituted Reaction Centers from Rhodopseudomonasviridis. Ferredoxin (FD) (E’ = – 430 mV): Using several experiments, including electron paramagnetic resonance (EPR), they were led to believe that pheophytin was reducible and therefore potentially the primary electron acceptor between P680 and plastoquinone. Answer. Due to the higher midpoint potential of plastoquinone in the Q A site than Pheo − the charge-separated state is stabilized, reducing the probability of a back reaction between Q A − and P680 + . primary electron acceptor of Photosystem II (PS II) taking electrons from the excited primary electron donor, chlorophyll P680, is a special form of bound plastoquinone (referred to as Q; also known as QA) with redox potential of −130 mV; its one-electron re-duction is accompanied by characteristic absorbance Phosphatidylglycerol Requirement for the Function of Electron Acceptor Plastoquinone Q B in the Photosystem II Reaction Center † Biochemistry, 2002 Gombos Zoltan It transports the protons to the lumen of thylakoid discs, while the electrons continue through the electron transport chain into the cytochrome b 6 f protein complex. A) Phaeophytin is the primary electron acceptor of PS II. Citations are the number of other articles citing this article, calculated by Crossref and updated daily.

PCC 6803 strain carrying mutations in the D2 protein. The Journal of Physical Chemistry Letters. The results show that a complex of plastoquinone and Fe can act as the stable “primary” electron acceptor in photosystem II reaction centers and that the interaction of its singly reduced form with the reduced intermediary acceptor, Pheo [unk], is responsible for the EPR doublet.
