Rate |
2. When was the rate the highest? Explain why.
3. When was the rate the lowest? Explain why.
4. Explain the inhibiting effect of sulfuric acid on the function of catalase. Relate this to enzyme structure and chemistry.
5. Predict the effect that lowering the temperature would have on the rate of enzyme activity. Explain your prediction.
6. Design a controlled experiment to test the effect of varying pH, temperature, or enzyme concentration.
