Protocol Lab #7 Purpose: To study the effect of pH on turnip peroxidase Scientific Hypothesis: Turnip peroxidase tested in a slightly acidic environment will have a greater reaction rate than that tested in a more acidic or more basic environment. Null Hypothesis: There will be no difference in reaction rate between turnip peroxidase tested in solutions of various pH. Predictions: 1. If turnip peroxidase is tested in an environment of pH 5, then there will be a fairly quick reaction rate. 2. If turnip peroxidase is tested in an environment of pH 2, then there will be little or no reaction. 3. If turnip peroxidase is tested in an environment of pH 6, then there will be an optimum reaction rate. 4. If turnip peroxidase is tested in an environment of pH 7, then there will be a fairly quick

Unformatted text preview: reaction rate. 5. If turnip peroxidase is tested in an environment of pH 9, then there will be a slow reaction rate. Rationales: 1. pH 5 is a slightly acidic environment, but is a little more acidic than optimal pH. Therefore the reaction rate will be quick, but not optimum. 2. pH 6 is a very slightly acidic environment. Therefore the reaction will be optimum. 3. pH 2 is a very acidic environment and may denature the protein in peroxidase. Therefore there will be little or no reaction. 4. pH 7 is a neutral pH. This is not acidic enough to create an optimum reaction rate. Therefore the reaction rate will be quick, but not optimum. 5. pH 9 is a slightly basic environment. This is too basic for a good reaction rate. Therefore the reaction will be slow....
