What predictions would you make about the enzyme activity if you were to continue to change each of the factors in Parts A – E? The predictions that would be concluded about the enzyme activity if it were to continue and change each of the factors in Parts A – E, would be that enzyme activity will decrease due to the optimal temperature, pH, concentrations, and metal salt concentration not being obtained. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? The changing of concentration of enzymes affects the rate of decomposition of H2O2 because increasing enzyme concentration will increase the rate of decomposition and decreasing enzyme concentration will naturally decrease the rate. The higher the concentration of an enzyme, the faster the rate of decomposition

Lowest?
The highest was at pH 7, and the lowest was at pH 2. The catalase enzyme works the best at an optimal pH of 7 (neutral) and works the worst at an acidic pH of 2.
How does changing the pH affect the rate of enzyme activity? Does this follow a pattern you anticipated?
A change in pH not only affects the shape of an enzyme but it also changes the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. If the enzymes pH is at an optimum level then the enzyme will work more efficiently so the rate of reaction will increase now as the pH changes away from the optimum the rate will decrease.
At what temperature is the rate of enzyme activity the highest? Lowest? Explain.
The highest rate of enzyme activity was the warm temperature. The warm was the highest because the enzyme was at a regular temperature where it was comfortable enough to have a good rate of reaction. The lowest one was hot temperature. This was because the enzyme was trying trying to move too fast and it was not able to react the right way because of the denatured
