ratios and rates within PS

[goegue at water.gm.ufz.de]

Hello,
can anybody help me? I am looking for informations about the
stoichiometry of PS II to Cyt b/f, of PS I to PC and of PS II to PS I
for PSU of eukarytic algae. Is the electron capacity of Cyt b/f
identically with the number of electron carriers in this complex. I am
also interested in the time of electron transit across the Cyt b/f.
Thank you and have a nice day
