8.1 Metabolism

Experiments

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

Inquiry

Analysis of Enzymes using Tyrosinase

Experiment #8 from Investigating Biology through Inquiry

In this Preliminary Activity, you will use a spectrophotometer to measure color changes due to the production of dopachrome and determine rate of reaction.

After completing the Preliminary Activity, you will first use reference sources to find out more about enzymes, tyrosine, and tyrosinase before you choose and investigate a researchable question. Some topics to consider in your reference search are:

  • catalyst
  • enzyme
  • substrate
  • tyrosine
  • tyrosinase
  • DOPA
  • Michaelis-Menten constant
  • Lineweaver-Burk plot
