Approximability of switch-effect by Hill-curve. Comparison between Hill-type response and the described switch effect. Plotted are steady-state values of R_{i_cie} or reaction velocity V (Hill-kinetics). Parameter and initial values used were the same as for Fig. 3C. Hill-parameters extracted from the stimulus-response curve were: h = 7.5, V _max = 1.0, K _m = 1.4.
