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;

#Section 2: General Biology
  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

Ethanol is produced by anaerobic fermentation of glucose by Saccharomyces cerevisiae. For the particular strain of S. cerevisiae employed, the maintenance coefficient is 0.18 kg kg- 1 h- 1, Yxs is 0.11 kg kg-1, YPX is 3.9 kg kg-1 and µmax is 0.4 h-1.  It is decided to investigate the possibility of using Zymomonas mobilis bacteria instead of yeast for making ethanol. Z. mobilis is known to produce ethanol under anaerobic conditions using a different metabolic pathway to that employed by yeast. Typical values of Yxs are lower than for yeast at about 0.06 kg kg-1; on the other hand, the maintenance coefficient is higher at 2.2 kg kg -1 h -1. Ypx for Z. mobilis is 7.7 kg kg-l; µmax is 0.3 h- 1.  From stoichiometry, what is the maximum theoretical yield of ethanol from glucose
