INVESTIGATING THE DIFFERENT CONCENTRATION OF CATALASE ON THE BREAKDOWN OF HYDROGEN PEROXIDE General Aim: My central aim is to find out whether the change in concentration of catalase (enzyme) affects the rate of oxygen produced. Scientific Theory on enzymes: Enzymes have an optimum temperature and pH at which they work best, this is the body temp. Enzymes are known as biological catalysts and are globular proteins with a tertiary structure, therefore they are very specific in the reactions that they catalyse. One enzyme will react with molecules of one substrate. The Active site where the reaction occurs is situated on the surface of the enzyme. The Active site for all molecules of one enzyme will be made up of the same arrangement of amino acids. Generally an enzyme molecules consists of one Active site and only one type of substrate have a complementary structure Enzyme reaction: Enzyme + Substrate Enzyme-Substrate complex Products + Enzyme (Transition...
