2. If a huge number of black balls were added will it change the maximum rate? Why?

3. Coloured balls were removed in **trial 2 ** . What does this simulate? How does that affect the rate of enzyme reaction? Increase concentration

4. How else could you change the rate of reaction?

5. Why does an active site not work as well if its active site is changed?

6. What environmental factors affect enzyme shape?

7. How might chemical affect you if they act like the tennis ball during your bodily reactions?
