WebbIf the enzyme molecule is irreversibly inhibited, such as by covalent addition of the inhibitor to the active site, that enzyme molecule no longer can participate in the reaction with substrate. Thus, the effective concentration of enzyme in the solution is reduced. Since Vmax is directly proportional to the enzyme concentration, Vmax decreases.
