Time dependency of the activated state yA for three different mixing intensities, Re = 0, 1000, 100000, with and without fast reduction, respectively. On the left, the time dependency of activated state yA of the reduced system (11) is shown for time range 0 - 40 s. On the right, the time dependency of activated state yA and inhibited state yB of the non-reduced system (7) is shown for time range 0 - 20000 s. The dynamics of activated state yA has two phases, fast phase (the transition from the initial value yA(t0)=0 to the maximal value occurring in seconds) and slow phase (imposed by the gradually growing inhibited state yB). In the case of applied fast reduction (left graph), the slow dynamics does not occur due to constant
