WebV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V_ {max} V max is called the K_m K m, and is a useful measure of how quickly reaction rate increases with substrate concentration. K_m K m is also a measure of an enzyme's ... WebActive sites and substrate specificity To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces.

WebThe ability of an enzyme to select a specific substrate from a range of chemically similar compounds is known as specificity. Since the enzyme and substrate exhibit complementary structural and conformational properties, specificity is a molecular identification process. Different enzymes exhibit different levels of substrate specificity.
