Philippa Brook 11SP Set S Investigation of the breakdown of Hydrogen Peroxide by enzymes in living tissue Plan and Research I am going to investigate the rate of reaction between enzymes in potato cells and them breaking down Hydrogen Peroxide, also looking at the effect temperature has on the experiment. Enzymes are present in all cells (usually the mitochondria) of living things. Catalase is the name of the main enzyme found in cells, depending on the tissue and which area of the 'body' it comes from determines how many enzymes are present (and in what concentration). Hydrogen peroxide (H2O2) is very unstable and will decompose breakdown slowly on its own, into water and oxygen, however a catalyst will speed up this reaction. Enzymes are catalysts; a catalyst alters the rate of a reaction, usually speeding it up. Catalyst are also not used up in a reaction, so can theoretically be used over and over again. They...
