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

The core antenna and P700 are bound to two proteins, PsaA and PsaB, with molecular masses in the range of 66 to 70 kDa
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
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
PSI is a multisubunits contains two of them is D and E, which carry +ve charge towards the lumenal side

As you study two closely related predatory insect species, the two-spot and the three-spot avenger beetles, you notice that each species seeks prey at dawn in areas without the other species. However, where their ranges overlap the two-spot avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them into the laboratory, their offspring behave in the same manner. You have discovered an example of
