The PSI reaction center complex is a large multi-subunit complex in which the antenna chlorophylls are associated with the reaction center Components of the PSI reaction center are organized around as follows choose the incorrect one;

#Unit 6. System Physiology – Plant
  1. The core antenna and P700 are bound to two proteins, PsaA and PsaB, with molecular masses in the range of 66 to 70 kDa
  2. PSI reaction center are organized around two major core proteins, PsaA and PsaB. Minor proteins PsaC to PsaN are labeled C to N and then to a chlorophyll molecule (A0) to (A1) Phylloquinone
  3. Electron acceptors include a series of three membrane-associated iron–sulfur proteins, also known as Fe–S centers: FeSX, FeSA, and FeSB,  Fe–S center X is part of the P700-binding protein; centers A and B are the part of minor protein C
  4. PSI is a multisubunits contains two of them is D and E, which carry +ve charge towards the lumenal side
