WebThe rate of enzymatic reaction depends on pH of the medium. Each enzyme has an optimum pH, where the rate of enzymatic reaction is maximum. At higher or lower pH, the rate of an enzymatic reaction decreases. For most enzymes, the optimum pH lies in the range from pH 5 to pH 9. WebMar 5, 2024 · There are a limited number of enzyme molecules and they can only perform a single reaction at a time. Thus, at high [S] the enzymes can be saturated. Under saturating conditions the reaction is going as fast as it can, and additional increases in [S] do not increase the reaction rate.
