Lab 4: Enzymes

The 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, Inhibitors

Experiments

Experiment 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.
