PLAN TO INVESTIGATE AN ENZYME-CONTROLLED REACTION. Prior to planning this experiment an introduction into enzymes and substrates was given. 14/11/02- Week 1 - Discussed enzyme structure and how they work. Properties of enzymes - Activation energy needed for A reaction with or without an enzyme present. Theories of induced fit and lock and key hypothesis. Enzyme/substrate complexes. 21/11/02 - Week 2 - Varying enzyme and substrate concentrations within a Reaction. A BBC computer was used to see how a varying enzyme/ Substrate concentration affects a reaction. A graph was presented on the computer to show rate of reaction The other factors which may affect an enzyme- Controlled reaction were discussed, temperature, pH, Competitive/Non competitive inhibitors. Again, the BBC computer was used to show how these factors influenced a reaction. A class demonstration was performed and observations made of an enzyme-controlled reaction using hydrogen peroxide and potato catalase. After an...
