Part A: The Effect of Temperature on Enzyme Activity
Graph the volume of oxygen produced against the temperature of the solution.
How is the oxygen production in 30 seconds related to the rate of the reaction?
At what temperature is the rate of reaction the highest? Lowest? Explain.
Why might the enzyme activity decrease at very high temperatures?
Why might a high fever be dangerous to humans?
What is the optimal temperature for enzymes in the human body?
Part B: The Effect of pH on Enzyme Activity
Graph the volume of oxygen produced against the pH of the solution.
At what pH is the rate of reaction the highest? Lowest? Explain.
Why does changing the pH affect the enzyme activity?
