Kinetic models of photosystem II should accommodate the effect of donor side quenching on variable chlorophyll a fluorescence in the microseconds time range
Quantitative data on laser flash-induced variable fluorescence in the 100 ns to 1 ms time range (Belyaeva et al. in Photosynth Res 98:105–119, 2008) confirming those of others (Steffen et al. in Biochemistry 40:173–180, 2001, Biochemistry 44:3123–3132, 2005; Belyaeva et al. in Biophysics 51(6):976–9...

Their data are conclusive with the involvement of donor side quenching, the release of which occurs with a rate constant in the range of tens of ms(−1), and presumed to be associated with reduction of [Formula: see text] by the OEC. |
