Description
| - In this work, we extended the reversible radical pair model which describes energy utilization and electron transfer up to the first quinone electron acceptor (Q(A)) in photosystem II (PSII), by redox reactions involving cytochrome (cyt) b(559). In the model, cyt b(559) accepts electrons from the reduced primary electron acceptor in PSII2 pheophytin, and donates electrons to the oxidized primary electron donor in PSII (P680(+)). Theoretical simulations of chlorophyll fluorescence rise based on the model show that the maximal fluorescence, F-M, increases with an increasing amount of initially reduced cyt b(559). In this work we applied, the first to our knowledge, metabolic control analysis (MCA) to a model of reactions in PSII. The MCA was used to determine to what extent the reactions occurring in the model control the F-M level and how this control depends on the initial redox state of cyt b(559). The simulations also revealed that increasing the amount of initially reduced cyt b(559) could protect
