Each enzyme have a pH where the enzyme is most active –which is known as the optimum pH. For most enzymes, the optimum pH lies in the range from pH 5 to pH 9. The optimum pH for . Jan 10, · Above or below an enzyme’s optimum pH, its activity is lower. The optimum pH of a particular enzyme corresponds to the pH of its natural environment. For many enzymes, this . Investigation of the effect of pH on enzyme. Invertase (sucrase) catalyses the hydrolysis of sucrose to glucose and fructose. Its activity has been demonstrated in bacteria, moulds, higher .Describe and explain the relationship between pH and enzyme activity. Practical materials specified on the Technical Information Sheet. Copies of the student worksheets. Preparation – 2 page student worksheet given out for students to read in preparation for the practical lesson. Jan 10, · Above or below an enzyme’s optimum pH, its activity is lower. The optimum pH of a particular enzyme corresponds to the pH of its natural environment. For many enzymes, this corresponds to pH values of around 7. For pepsin, which is active in the stomach, the optimum pH is 2 (the pH of the stomach). Calculate the rate of enzyme reaction by using 1/ time taken for iodine solution to remain brown. Repeat steps for buffer solutions with different pH values. Plot a graph of the rate of enzyme reaction against pH.
