Figure 4: Bifurcation plot displaying the effects of different input modes on ΔP versus variations in K3 for enzyme catalysis with substrate activation. k1=0.01, k2=0.1, k4=1, k5=0.1, Etotal=0.5. The graph for a sinusoidal input with K3 ranging from 13 through 15 is overlaid on the graph for square input ( alternates between 1 and 0).
