Learning objective Time taken Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources Enzyme catalysis and activation energy. The induced-fit model of enzyme action. Enzyme specificity linked to active site structure. 0.2 weeks Interpret energy diagrams and identify the activation energy. Explain the induced-fit model of enzyme action. Apply knowledge of tertiary structure to explain enzyme specificity and the formation of enzyme-substrate complexes. Learning activities: practical demonstration of how long it takes to decompose hydrogen peroxide using manganese(IV) oxide in one tube, liver or potato in another and no catalyst in a third teacher explanation of activation energy and induced-fit model, using animations or videos exam questions. Skills developed by learning activities: MS 1.3 – interpret graphs of energy changes during reactions, to identify activation energy AO1 and AO2 – demonstration and application of knowledge of scientific idea AO3 – interpret scientific information and ideas to make Past exam paper material: BIOL1 June 2009 – Q3a and 3b BIOL1 Jan 2011 – Q2b June 2010 – Q5 Rich questions: what aspects of enzyme catalysis cannot be explained using lock and key? why is induced-fit a more refined model of enzyme catalysis than lock and key? Students could also extend their learning by researching why the specificity of enzymes in catalysing reactions makes them useful in industrial processes and biosensors.
