An Investigation into the Rate of Breakdown Of Hydrogen Peroxide By Potato Tissue Initial Observations: - 1) Hydrogen peroxide solution is toxic. 2) Hydrogen peroxide slowly beaks down to oxygen and water. 3) All living cells contain the enzyme catalase. 4) Catalase/living cells cause hydrogen peroxide to break down quickly. Hypothesis: - I predict that the greater the surface area the more oxygen will be produced in the first five minutes of collecting oxygen. Each enzyme has an active site, which is an area of a particular shape into which only one type of molecule will fit. For this reason enzymes are specific to their substrate. The enzyme catalase splits hydrogen peroxide as follows: - hydrogen peroxide oxygen + water 2H O O + 2H O The above reaction will only occur when the hydrogen peroxide molecule collides with a catalase molecule. The more collisions there are, the larger the volume of oxygen produced. If the...
