Student evaluation of which model is stronger and why. Learning objective Time taken Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources The properties of an enzyme relate to the tertiary structure of its active site in the formation of an complex. The effects of the following factors on the rate of reactions – enzyme concentration, substrate concentration, concentration of competitive and of 1 week Explain how temperature, pH, substrate concentration, enzyme concentration and the presence of inhibitors affect enzyme catalysis. Describe and explain trends within graphs, relating this back to the tertiary structure of active sites and the effect of these variables. Learning activities: conduct investigations relating to each variable (leave one to be conducted as full investigation in next section) get students to calculate rate and produce graphs for each practical teacher explanation of trends within graphs for each factor exam questions.
