This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to explain the action and importance of digestive enzymes.

Objectives

Students will be able to

  • describe the sites of production and the action of amylases, proteases, and lipases,
  • explain the importance of enzymes in breaking down long molecules in digestion,
  • state the monomers of proteins, lipids, and carbohydrates as amino acids, glycerol and fatty acids, and sugars respectively.

Prerequisites

Students should already be familiar with

  • the fact that the process of digestion is how humans break down food to release nutrients,
  • the basics of the lock-and-key theory of enzyme action.

Exclusions

Students will not cover

  • the detailed structure of biological molecules,
  • hydrolysis and condensation reactions,
  • the effect of pH/temperature/substrate concentration on enzyme-controlled reactions.
