Enzymes are so important to our lives that a single amino acid mutation in one enzyme out of the more than 2000 enzymes in our bodies can result in a severe or lethal genetic disease. Figure 6.1: A Michaelis-Menten reaction of two substrates converting to one product.Similar results are obt,ained when the initial rates are enhanced with increases in either enzyme or lactate concentrations. Kinetics of this sort is reminiscent of second order autocatalyzed reactions such as hydrolysis of esters (5, S), and suggests that the concentration of a product of the reaction is a factor in the rate law that the ...

The Michaelis-Menten equation assumes a simple reaction of the form: E+ S − ⇀ ↽ − ES E + P. where E is an enzyme, S is the substrate, and P is the product. Note the formation of the intermediate enzyme-substrate complex, ES, which is a transition state (recall Figure 3.3.2) in which the substrate is unstable and associated with the enzyme.
