Questions
1. What is the enzyme in this experiment? (2 pt) What is the substrate? (2 pt)
2. Did you notice a difference in the rate of reaction in the tubes with different concentrations of
enzymes? (1 pt) Why or why not? (3 pts)
3. What was the effect of using less enzyme on your experiment? (3 pts)
4. Do you expect more enzyme activity if the substrate concentration is increased or decreased? (2 pt)
5. Hydrogen peroxide is toxic to cells, yet is a common byproduct of the reactions that occur inside the body. How can this compound by changed to become non-toxic? (4 pts) (Hint: Look at the
chemical formula of hydrogen peroxide)
