How does enzyme affect velocity of reaction

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.
