To Investigate the Effect of Varying pH on the Rate of a Reaction Catalysed by Trypsin Aims I hope to determine the effect of varying pH on the rate of reaction catalysed/controlled by the enzyme trypsin. Method 1. Add 4cm³ of the 2% trypsin solution in to 6 test tubes labelled A-F 2. Add 4cm³ of the appropriate buffer solution to each. ( I will be testing pH 4‚5‚7‚8‚8.8 and 10) 3. Add 4cm³ of distilled water and 4cm³ of the appropriate buffer solution to 6 control test tubes labelled CA-CF to see
