Abstract

Light energy absorbed by a Ch1 molecule creates an exciton which can produce photochemistry, heat or fluorescence. Fluorescence lifetime measurements have demonstrated that the observed fluorescence is a sum of several lifetime components. We present evidence that:
  1. 1)

    The fluorescence lifetimes are trap-limited in both PSI and PSII

     
  2. 2)

    PSII fluorescence decays with biexponential kinetics

     
  3. 3)

    Separate fluorescence lifetime components can be observed from PSII-alpha and PSII-beta
