At what temperature does Catalase work best at? Aim: To see what temperature Catalase works better at. Prediction: I predict that at a low temperature the Catalase will work slowly but the work rate will increase as the temperature does.

Background information: Enzymes: * Are Complex proteins that cause a specific chemical change in other substances without being changed themselves.
