Lesson Plan: Metabolism and the Liver Biology

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define metabolism and describe the metabolic functions of the liver.


Students will be able to

  • define metabolism and give examples of metabolic reactions,
  • define the terms catabolism and anabolism,
  • describe the role of the liver in removing lactic acid after lactic acid fermentation (anaerobic respiration in body cells).


Students should already be familiar with

  • respiration as a reaction that occurs in the human body,
  • the fact that waste products should be removed from the body.


Students will not cover

  • the effect of thyroxine on metabolism.
