Summary Introduction

To review:

The Km value for the inhibited and uninhibited reactions using a Michaelis–Menten plotis to be determined. The data for the enzyme-catalyzed hydrolysis reaction in the presence and absence of inhibitor is given as follows:

Substrate (moles) V0 (micromoles per minute) V0I (micromoles per minute)
6×106 20.8 4.2
1×105 29 5.8
2×105 45 9
6×105 67.6 13.6
1.8×104 87 16.2

Introduction:

The Km value is defined as the substrate concentration at which half of the maximum velocity (1/2 Vmax) is achieved in the reaction. The inhibitors can be competitive (increase the Km value), uncompetitive (decrease the Km value), or non-competitive (do not alter the Km value), depending upon the mechanism used to inhibit the activity of the enzyme. The inhibitors act by decreasing the rate of a catalyzed reaction by interacting with free enzyme, enzyme–substrate complex, or both.
