AS INTERNAL ASSESSMENT Investigating How the Concentration of the Enzyme Catalase in Celery Tissue Alters the Rate of Reaction with Hydrogen Peroxide. I am going to investigate how the concentration of an enzyme (the enzyme catalase) affects the rate of reaction it is involved in. To investigate this problem, a knowledge of enzymes and more specifically the enzyme catalase (or peroxidase) is required. Enzymes are described as biological catalysts. Like any catalyst, enzymes help to speed up chemical reactions without actually being altered by the reaction. If you wrote down the equation of an enzyme or indeed any catalyst-controlled reaction the molecules in the enzyme would not appear as part of the equation, but are written above the line indicating the direction of reaction. This means that enzymes help to speed up reactions, which occur naturally but very slowly and can be used time and time again as they are not altered...
