Due Wednesday 18th November.
Use the following:

To answer the following questions in your book.
1. Describe the relationship between substrate concentration and the reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the reaction rate as substrate concentration increases?
2. What is the maximum reaction rate for the lactase enzyme at pH 7?
3. Explain why the maximum reaction rate cannot be reached at low lactose concentrations.
4. What does your data indicate about the optimum pH level for this lactase-catalyzed reaction?
5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate. Explain.
