An Investigation to determine the effect of Substrate Concentration on the Enzyme Catalase AIM The aim of this assignment is to determine and prove with evidence from experiments, how the substrate concentration of Hydrogen peroxide affects the rate of reaction of the enzyme Catalase. BACKGROUND - ON BIOLOGICAL CATALYSTS, ENZYMES Many chemical reactions in living organisms would occur very slowly, if we did not have special catalysts, which is a substance that lowers the activation energy required for a reaction, and therefore increases the rate of the reaction without being used up in the process. Enzymes are biological catalysts, responsible for metabolism and its regulation within living organisms. These molecules have catalytic sites onto which substrates fit in by using a lock-and-key manner to trigger and control metabolism throughout the body. DIAGRAM 1 (A DIAGRAM SHOWING A TYPICAL STRUCTURE OF AN ENZYME, GLOBULAR PROTEIN) Enzymes are globular proteins, which are coiled into a...
