Aim I am going to investigate how the temperature affects the catalyse enzyme on hydrogen peroxide, using potato discs for the catalyse. Hypothesis Catalyse is a biological enzyme which works best between 30 and 40 degrees, like most enzymes. It also has an optimum pH. Catalyse breaks down Hydrogen Peroxide into water and oxygen. Plant and animal cells contain catalyse. `I predict that the catalyse enzyme found in the potato will break down the substrate (Hydrogen Peroxide) quickest at 37- 40 degrees Celsius because enzymes work best at certain temperatures, usually body temperature. If the temperature is above 40 degrees the enzyme will become denatured so molecules of Hydrogen Peroxide won't be able to fit into it and so they can't form an enzyme substrate complex and can't be broken down, so no oxygen or water is created. If it is below 37 degrees the amount of activity is reduced, as temperature is a limiting...
