An investigation to see how much oxygen was produced in the reaction between Hydrogen Peroxide and catalyse. Aim: To investigate the amount of oxygen given off when 100ml of Hydrogen Peroxide is added to two pieces of potato (each 2cm in length). An enzyme (PH7 on the PH scale) breaks down a substrate. The substrate we are using is hydrogen peroxide solution and the enzyme is catalysing (potato). Catalyse breaks down the hydrogen peroxide into water and oxygen; H202 --> 02 + H20. I will take 5 readings and repeat them, by this I will hopefully see patterns and trends more clearly and compare and identify the results. I will also be using different concentrations of hydrogen peroxide to see what effect it has on this process. Background information: An enzyme is a biological catalyst which speeds up reactions within all living things. Enzymes and substrate fit together like a lock...
