Catalase is a very fast reacting enzyme, it is found in many living cells, it breaks down hydrogen peroxide to water and oxygen. One molecule of it can deal with six million molecules of hydrogen peroxide in 1 minute. Hydrogen peroxide is toxic so needs to be changed into harmless substances. Catalase break down Hydrogen peroxide water + oxygen 2H2O2 2H2O + O2 I have been set the task of finding out how the surface area affects the rate of catalase action. In my preliminary testing I found out which size of measuring cylinder to use for the final test and what condition would be the best. Whilst all of this I had to make the test as fair and accurate as I could by measuring all the liquids and measuring of potato accurate. I have carried out some preliminary testing to experiment how the surface area affects the rate...
