Enzyme Action: Testing Catalase Activity


Questions

  1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2?
  2. If one increases the concentration of enzyme to five drops, what do you think will happen to the rate of reaction? Can you predict this rate? If so, please show your logic.
  3. At what pH is the rate of enzyme activity the highest? Lowest?
  4. How does changing the pH affect the rate of enzyme activity? Does this follow a pattern you anticipated?
  5. At what temperature is the rate of enzyme activity the highest? Lowest? Explain.
  6. How does changing the temperature affect the rate of enzyme activity? Does this follow a pattern you anticipated?
  7. Why does the enzyme activity decrease at very high temperatures?
  8. Summarize your conclusions of this laboratory experiment. Use your data to answer the purposes of this experiment.
