WebThe optimum pH for the reaction of starch with amylase is pH 7. PH values lower or higher than this value will result in a slower rate of reaction. Amylase works in the range pH 3 to pH 11. PH changes affect the structure of an enzyme molecule and therefore affect its ability to bind with its substrate molecules. WebFor example, for the pH 5 investigation, the calculation would be: 1 ÷ 120 = 0.0083 So, from the results: Plot a graph of rate of reaction against pH. A similar experiment can be …
