Enzynes
Please see the attachedLab 4: EnzymesThe properties of the enzymes are investigated in these experiments. Students will explore factors that can affect enzymatic activity.Time: 1 hour (plus 2 hours preparation time)Concepts to explore: Enzymes, Selectivity, Catalysts, Activation energy, Activation site, Reaction sites, Activators, InhibitorsExperimentsExperiment 1: Effect of Enzyme Concentration Students investigate the effects of catalase concentration on the amount of oxygen produced by yeast cells mixed with H202.Experiment 2: Effect of temperature on Enzyme Activity Students study the role of temperature in enzyme function.Experiment 3: Enzymes in Food Students identify foods that contain the enzyme amylase.
