Biology Coursework Investigating the effect on the enzyme Catalase Aim To discover how temperature will effect the speed in which the enzyme Catalase will react with Hydrogen Peroxide. Background Information Individual enzymes are named by adding ase to the name of the substrate with which they react. The enzyme that controls urea decomposition is called urease; those that control protein hydrolyses are known as proteinases. Some enzymes, such as the proteinases trypsin and pepsin, retain the names used before this nomenclature was adopted. * They are all proteins * They are specific in their action, one enzyme speeding up one reaction only. * They work within only a narrow range of acidity or alkalinity. * Heat alters enzymes so they work at different rates. At certain high temperatures enzymes denature. * They can be used over and over again. * They all require water before being able to function. * Living cells are the only producers of enzymes. * The enzyme molecule is...
