Title: Inhibitory of copper Sulphate on enzyme catalase found in Liver Aims: Investigating the affect of Copper Sulphate on Liver. Hypothesis: Catalase is a red crystalline enzyme that consists of a protein complex with a haem groups in the centre. Catalase catalyses the decomposition of hydrogen peroxide into water and oxygen: 2H2O2 2H2O + O2 An enzyme inhibitor is a substance that slows down the rate at which an enzyme-catalysed reaction takes place. Many enzyme inhibitors work by binding with the enzyme, with the result that the enzyme can no longer bind with its substrate Some inhibitors have shapes rather like the enzyme's normal substrate molecule, allowing them to bind at the active site of the enzyme. They are called active site-directed inhibitors. If there is an inhibitor molecule in the active site, the substrate cannot bind there. Some active site-directed inhibitors bind permanently to the active site, so that they permanently inactivate the enzyme....
