Enzyme Design Lab
Research Question:
At what temperature does an enzyme react at its optimum rate?

Background Information:
Hydrogen Peroxide is a by product of many biological and chemical functions of organism. Although it is toxic, it still remains in our cells. To counter the hydrogen peroxide we produce something called a catalase. This means that with a catalase, it can cause the chemical reaction to speed up the reaction of the Hydrogen Peroxide so that it does not come in contact with our cells. The enzymes that are being used in this lab, whichever catalase it may be, has an optimal or room temperature of 37°C. When the the chosen enzyme catalase is exposed to hydrogen peroxide, it begins to decompose into the water mixed with the oxygen gas in the air. This means that when an enzyme is damaged, it is no longer able to work as a catalyzer in a chemical reaction.
When the potato is placed in the hydrogen peroxide mixture the reaction will happen once the start of bubbles arise and the metabolic reaction process of decomposition. This will happen because the reaction is caused by the catalase and the enzyme within the potato.

Hypothesis:
If we heat up the water to a temperature higher than room temperature, then the length of reaction will increase.
