Introduction/How does catalase work? Our brief for this experiment was; "To see how concentration of a solution affects the enzyme activity." To perform this practical experiment, we are going to use Hydrogen peroxide, and alginate (which is basically a yeast ball containing catalase, an enzyme). Enzymes exist in all living things. They are composed of polymers of amino acids and are produced in living cells. Each cell contains several hundred enzymes, which Catalase a vast number of chemical reactions. Enzymes are known as Biological Catalysts as they dramatically increase the rate at which reactions occur within living organisms, without being 'used up' or effecting the reaction in any other way. Enzymes catalysis saves the need for an increase in temperature in order to speed up reactions within living things. Such an increase in temperature would be lethal to the organism. Enzymes such as Catalase are protein molecules, which are found in living cells....
