B.2 Proteins and enzymes


Here are experiments our science specialists have selected to support the IB* topic.

Enzyme Activity

Experiment #23 from Investigating Chemistry through Inquiry

In the Preliminary Activity, you will use catalase in yeast to catalytically decompose hydrogen peroxide. You will determine the rate of enzyme activity by measuring the pressure of oxygen gas produced as H2O2 is decomposed.

After completing the Preliminary Activity, you will first use reference sources to find out more about enzymes and enzyme activity before you choose and investigate a researchable question dealing with enzyme activity.

Liquid Chromatography

Experiment #18 from Advanced Chemistry with Vernier

In this experiment, you will

  • Conduct an isocratic, liquid-chromatographic separation.
  • Conduct a step gradient, liquid-chromatographic separation.
  • Complete the necessary measurements and calculations to evaluate the components of a mixture that have been separated by liquid chromatography.
