So our first type of inhibitor is called the competitive inhibitor, and it works by binding to free enzyme, or E, to form EI, or enzyme inhibitor complex. That is, suitable method should be used to minimize the effect of the error of data. In this example, the instructor will derive the rate expression for a Michaelis-Menten kinetics where an enzyme reacts with a substrate in a reversible reaction to form an enzyme-substrate complex.
