Simulate+the+Enzyme-Substrate+Model

** QUESTIONS **
//Answer these questions in your online journal.// 1. In **trial 1**, why did the rate eventually decrease? What could have been added to maintain the initial rate? 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? 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?

Black ball**- substrate
 * Note:
 * Coloured ball**- water
 * Hand**- active site
 * Tennis ball**- inhabitant

1) As more black balls were taken out, the number of coloured balls in comparison to the black balls was more. This means that the concentration of the substrate decreased, while the concentration of water increased. The 'solution" becomes more diluted, and there is a lesser chance for enzymes to collide with the substrate. Thus, the rate decreased. However, the rate can be increased if more substrate was added inside(add mroe coloured balls), or decreasing the amount of water(decreasing the number of coloured balls).

2) If a huge number of black balls were added, the rate will be faster as a higher concentration of substrate increases the chances of collision with enzyme, and thus a faster rate of digestion.

3) The higher the concentration of the substrate, the faster the rate of reaction/digestion as there is a high chance of collision between the substrate and the enzyme. As more coloured balls were taken out, more black balls were present (in comparison to the coloured balls). This means that the concentration of substrate is higher. Thus, the rate of enzyme reaction became faster as the concentration increased this allows a higher chance of collision between the enzyme and the substrate.
