Catalase Demo Questions
1. What is an enzyme?
2. In this demo we tested the rate at which catalase can break down the poisonous chemical hydrogen
peroxide in our bodies. What is the enzyme, and what is the substrate?
3. Write the chemical equation for the breakdown of hydrogen peroxide.
4. What do we call it when an enzyme looses its shape? What are 2 ways this could happen?
5. When the enzyme Catalase and the hydrogen peroxide solution reacted, what gas was being released?
6. Assuming that the reaction had enough time to finish, what should the liquid be that remains in the test
tube? Would there be a reaction if more Catalase was added?
7. Are enzymes reusable? What happened when more hydrogen peroxide was added to the used piece of
liver?
8. What does boiling do to an enzyme?
9. What was the optimum temperature for the Catalase enzyme? Explain what happened at each
temperature we tested.
