Effect of temperature on the action of the enzyme catalase AIM- Effect of temperature of the action of the Enzyme Catalase. PLANNING Background Knowledge An enzyme is a biological catalyst, it alters the rate of reaction without being changed itself. Enzymes are proteins; they have a very precise three-dimensional shape, which forms a one specific active site on the enzyme. Each enzyme can only convert one kind of substrate molecule in to one kind of product molecule. These are specific. What affects Enzymes? ˇ Temperature- Enzymes stop working if the temperature rises above 40ēC. Increasing the temperature alters the 3D shape and so the enzyme can no longer fit the substrate. ˇ pH- They work best in neutral conditions neither acidic nor alkaline. What affect does catalase have? Catalase is a very fast reacting enzyme; it is found in many living cells, it breaks down hydrogen peroxide to water and oxygen. In fact one molecule of it can...
