BIOLOGY COURSEWORK Experiment to investigate how the change of temperature affects the catalase controlled breakdown of Hydrogen Peroxide PLANNING Background Knowledge An enzyme is a biological catalyst, it alter the rate of reaction without being changed itself. Enzymes are protein molecules; they have a very precise three-dimensional shape, which forms a one specific active site on the enzyme. Enzymes can only catalase one reaction or type of reaction, they are specific. Enzymes are affected by temperature (Enzymes stop working if the temperature rises above 40°C. Increasing the temperature alters the 3D shape and so the enzyme can no longer fit the substrate) and pH (They work best in neutral conditions neither acidic nor alkaline). Equipment Core Borer Potato 4 boiling tubes 125 ml Hydrogen Peroxide Ice cream tub, half filled with water of room temperature Two wooden Blocks Clamp stand Thermometer Beaker Bunsen Burner Bung and delivery tube Test tube Test tube rack Stopwatch Knife Tile Ruler Measuring Cylinder Heatproof mat Matches Goggles Lab Coat Method * Using the Core borer bore out five pieces of potato from...
