Aim: To investigate one factor which affects the way in which the enzyme catalase works. catalase Hydrogen peroxide ? oxygen + water 2H2O2 (aq) O2 (g) 2H2O(l) Background: There are three main ways to affect the way and speed that the enzyme catalase works. One is to change the temperature at which it is used. This affects the rate of reaction at which hydrogen peroxide is broken down because enzymes act like inorganic catalysts, and the rate of reaction doubles every 10?c within the temperatures of 0 and 40?, but above this temperature the enzymes effectiveness slows, and then stops as it becomes denatured. The optimum temperature is around 37?c, as this is the average body temperature and enzymes are designed to work in the body. For a reaction to occur, particles need to collide successfully. For a successful collision, molecules need to collide with enough energy to break the bonds. This is...
