What factors affect the activity of Catalase?
The study of the rate at which an enzyme works is called enzyme kinetics. The rate at which an enzyme works is influenced by several factors including the concentration of substrate (hydrogen peroxide in the case of catalase), temperature, pH, salt concentration and the presence of inhibitors or activators. Every enzyme has an optimal range for each of these factors. Activity decreases when an enzyme is exposed to conditions that are outside the optimal range. Substrate Concentration: If all other conditions are held constant, the rate of the reaction should increase with increasing concentrations of substrate. At very low values of substrate the reaction rate will increase very rapidly. At higher substrate concentrations the rate begins to level off. Eventually the maximum rate for that reaction will be achieved and further increases in substrate concentration will have no effect. Temperature: In general, chemical reactions speed up as the temperature is raised. When the temperature i
