... Biology Investigation - Hydrogen Peroxide and Enzymes. Aim of my investigation To see how different concentrations of Hydrogen Peroxide and water affects how much oxygen is given off in froth measured in volume (cm3), from 5cm3 of minced pigs liver (which contains catalyse) when mixed. Background information Catalase is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and oxygen. You can represent this in the equation: 2H2O2 =2H2O + O2 Enzymes: Enzymes are able to increase the rate of reaction without actually being consumed in the process. In all, enzymes are very efficient. Small quantities at low temperatures are able to produce results, which would require high temperatures and a violent reaction from any normal chemical means. Although increases in temperature may speed up the reaction, enzymes are unstable when heated. There are three important definitions that are used when talking about enzymes: - The substance that enzymes act on
