The effect of Temperature on Enzymes Aim: To investigate the effect of temperature on the breakdown of starch by amylase, and to find the optimum temperature for the reaction. Research: Enzymes are proteins that control vital biological processes. They often act as biological catalysts. They are made in cells. A catalyst is a chemical substance which speeds up a reaction but does not get used up during it. One enzyme molecule may be used several times over. If starch is mixed with water it will break down very slowly into sugar, taking several years, however, in your saliva there is an enzyme called amylase which can break down starch to sugar in minutes or seconds. A rise in temperature increases the rate of most chemical reactions and a fall in temperature will slow them down. In many cases a rise in 10¦ C will double the rate of reaction in a cell. This is particle...
