AIM
Effect of temperature of the action of the Enzyme Catalase.

Background Knowledge
An enzyme is a biological catalyst, it alter 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?
· Temperature- Enzymes stop working if the temperature rises above 40ºC. Increasing the temperature alters the 3D shape and so the enzyme can no longer fit the substrate.
· 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 deal with six million molecules of hydrogen peroxide in 1 minute. Hydrogen peroxide is toxic so needs to be changed into harmless substances.
