The Initial Velocity of an Enzyme Reaction - Cell Biology

WebAn enzyme is a biological catalyst. It speeds up a reaction by lowering or reducing the activation energy of the reaction. It can increase the rates of both forward and backward … 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. crystal court apartments lakeland
