1. An enzyme has a Km of 4.7x10-5 M. If the Vmax of the preparation is 22 µmoles. Litre -1.min.-1. What velocity would be observed in the presence of 2x10 -4 M substrate and 5x10 -4 M of a) Competitive inhibitor b) a non-competitive inhibitor c) an uncompetitive inhibitor. KI in all three cases is 3x10 -4 M. d). What is the degree of inhibition in all three cases?​
