Plots of the steady state solutions for A and B. Parameter values: λ1 = 0 (solid), λ1 = 0.01 (dash). Other parameter values: λ2 = 1, λ3 = 0.5 λ4 = 10, λ5 = 12, μ
= 10, μ
= 0.2, δ
= 0.02, δ
= 0.1. Compared to Fig. 7, we observe that decreasing the level of b (through increasing λ4) increases the concentration of a, since the rate of complex formation is reduced.
