2) Explain how an enzyme functions as a catalyst?

3) How can an enzyme be specific for a specific substance? What makes it work only for that substance?

4) What factors affect enzyme activity?

5) Predict the effects of temperature, concentration of enzymes, and pH on the activity of enzymes. Make relationship statements such as, "As temperature rises, enzyme activity will........
