How temperature affects the Catalase enzyme
The hypothesis that at temperatures above 40°C, the enzyme catalase will become less effective, is proven to be true. Enzymes are made of proteins which will become unstable at higher temperatures. As the shape and structure of the catalase enzyme changes, its effectiveness as an enzyme is reduced.
Besides playing an important role in the preservation of life in living organisms, the catalase enzyme also has commercial uses. In the food industry, it is used to milk free from hydrogen peroxide content, so that the milk can be used to make cheese. In the textile industry, it is used to remove hydrogen peroxide from cloth.
What will happen if the experiment is repeated using different amounts of hydrogen peroxide in the test tubes?
The experiment can be repeated using liver tissue instead of potatos.

Be careful when using the hot plate.
