Description	Decay processes of higher S-states occurr in long time scale in case of cyanobacteria. In order to examine these processes, we have tested the simplified and improved models of photosystem II (PSII). Either continuous or flash light regime was applied, followed by dark period where the S2,3-decay was analyzed. The simplified model matched the experimental data, however, this model disconnects the particular donor and acceptor sides of PSII, in comparison to the improved model. The simulations based on the improved model showed that the charge recombination, even assuming reduced plastoquinone pool in the dark (due to respiration), cannot match the measured flash-induced S3-state decay and the S2-state is accumulated in the dark if the continuous light is applied. Our analysis indicated three options: (1) the simplified model is correct and the inter-monomer recombination occurs between PSIIs, or (2) the improved model is correct, part of the higher S-states is stable in the dark and the source of the faster S3-state decay are impurities/chemicals in the experiments or (3) the improved model is correct and the cooperation between PSIIs in dimmer is a partial source of the S3-state decay.
