WebThe Effect of Temperature on Enzymes. Planning. Introduction: An Enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. Those enzymes identified now number more than 700. Web4. pH – the rate of reaction of enzymes varies with pH, due to changes in the shape of the active site. An enzyme would have the highest rate of reaction at its optimum pH. A buffer might be used to maintain pH at a suitable level. Temperature – the rate of reaction of enzymes varies with temperature.
