360Science™: Peroxidase Enzyme Activity

firewatch

In this lab, students will explore the rate of enzyme-catalyzed reactions by measuring the absorbance or color intensity of the orange product formed from guaiacol and hydrogen peroxide as a function of time for three different concentrations of turnip peroxidase.

Concepts

  • Enzyme structure and function
  • Kinetics and rate laws
  • Enzyme−substrate binding
