Biology Coursework Elliot Murphy Aim: I will choose one factor of this reaction and record how it affects the rate of reaction. The enzyme Catalase causes the following reaction: Hydrogen peroxide Water + Oxygen 2H2O(aq) 2H2O(aq) + O2 (g) Background Information: Catalase is an enzyme. Most enzymes are proteins and all are catalysts. Enzymes either break molecules down or build them up. Most enzymes work at the optimum temperature of 36°C (body temperature). Any lower than this and the rate of reaction will decrease. If the temperature gets too high, the enzyme becomes denatured and will cease to work. Denatured is when the shape of the active site changes, disallowing it to combine with the specific molecule, meaning no reaction will take place. Different enzymes have different optimum pH levels but all will become denatured if the pH level is too high or too low. Enzymes are constant throughout a reaction and will remain afterwards....
