Lesson: Enzyme Action Biology

In this lesson, we will learn how to describe the properties of enzymes and outline the lock-and-key theory of enzyme action.

Lesson Plan

Students will be able to

describe the properties of enzyme molecules as being biological catalysts that are not used up in a reaction,
explain enzyme action in terms of the lock-and-key theory,
state that enzymes can be denatured due to changes in their active site.

Q1:

Fill in the blank: The reactant that an enzyme will bind to, due to its complementary shape, is a/an .

Q2:

Enzymes act as catalysts. What does a catalyst do?

Q3:

With reference to enzymes, what does “denatured” mean?
