4A_Enzymes

1. In ** trial 1 **, why did the rate eventually decrease? What could have been added to maintain the initial rate? This was because there were less black balls in the sea of coloured balls, so the chance of picking a coloured ball is decreased.

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? By removing more coloured balls, the concentration of black balls is increased. Therefore, the chance of picking a black ball is increased. The coloured balls are water mol  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?
