Lesson Plan: Enzymes Biology • Second Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the action of enzymes in catalyzing biological reactions.
Objectives
Students will be able to
- recall that enzymes are proteins,
- describe how enzymes act as biological catalysts for certain reactions, which are usually reversible,
- explain that enzymes will only catalyze certain reactions due to the need for the enzyme and its substrate or substrates to have a complementary shape,
- recall that some enzymes are secreted in inactive forms and must be activated,
- state that pH and temperature can affect the activity of enzymes.
Prerequisites
Students should already be familiar with
- proteins as biological macromolecules.
Exclusions
Students will not cover
- details of the lock-and-key theory,
- the induced-fit model.
