Activity Overview

In this activity, students understand the relationship between enzyme reaction rates and various environmental factors such as pH and temperature. They recognize the metabolic differences between endotherms and exotherms. They generate graphs by inputting reasonable data modeling enzyme activity rates.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 25 - 30 from the attached PDF file for your class

    		•

    		During the Activity

    		Distribute the pages to your class.

    Follow the Activity procedures:
  • Examine the enzyme activity versus pH and enzyme activity versus Temperature graphs
  • Note how enzyme activity relates to pH and temperature
  • Relate the data to biological systems and organisms
  • Plot a graph of the metabolic rate of an exotherm and an endotherm

    		After the Activity

    		Students will complete Student Data Collection and Analysis Sheet.

    Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
