Fig. 7-5. Effects of noncompetitive inhibition on a monolinear chain A-^B->C. 

 Curves 1 and 2 in each case show the rates of reaction 1 and reaction 2, respec- 

 tively. The dashed curves, labeled either 1, or 2^, show the rates of these reac- 

 tions following inhibition. The horizontal dashed line labeled v,t indicates the 

 steady-state rate and cuts the curves at the concentrations of A and B in the 

 steady-state. When reaction 1 is inhibited this line is lowered to that indicated
