What effect does the temperature of water have on the catalyses of potatoes?

Claim: Warm temperatures speed up the reactions. Extreme high temperatures and extreme low temperatures slow the reaction. The height of bubbles was most significant when at ice temperature (5).

Evidence:

Question: What affect does pH have on the enzymatic activity of catalase in potatoes?

Claim: It appears as though there is no statistically significant difference between levels of pH and enzymatic activity. The enzyme activity, shown by oxygen production, was not very spread showing relative consistency among pH's.

Evidence: The standard deviation and standard error is relatively low resulting in the fact that the spread of the data is also relatively low despite the fact that pH levels varied. However, based on the graph it appears as though there is a positive correlation between pH and oxygen production. This however does not mean causation because there may also be other factors affecting reaction production.

Question: How do different sources of catalase affect the reaction rate of hydrogen peroxide breakdown?

Evidence:
Mean of the Means - Intensity of Bubbling
Potatoes: 3.883
Chicken Blood: 2.333
Peroxide: 1

Standard Deviation: 1.417
Standard Error: 0.818

Claim:Chicken blood appears to have an immediate reaction to the peroxide, while potato seems to have a longer and drawn out reaction. Peroxide simply has no reaction. The reason that potato takes longer is because potatoes have cell walls which are harder to break down than the exposed blood.

Question: What effect does temperature have on catalyses?
Claim: Extreme high and low temperatures slow the reaction. Highest results came from the room temperature.
