While some of the presentation may seem somewhat dated, the basic concepts are still helpful for researchers who must use enzymes but who have little background in enzymology. Post Comments. One benefit of enzyme catalysts is that the cell can carry out complex chemical activities at a relatively low temperature. The Michaelis constant (Km) of an enzyme identifies the substrate concentration at which 50% of the enzyme active sites, on average, have substrate bound to them. enzyme and subsequently be released, leaving the enzyme in its original condition. The interaction kinetics can be subdivided in three distinct  In enzyme kinetics, V represents the reaction velocity and S is the substrate. These sites usually involve weak, reversible bonds (such as hydrogen bonds) between substrate and enzyme. In the study of substrate concentration on enzyme kinetics, the enzyme is kept constant where as the concentration of Starch is taken in increasing order.
