Introduction to the lesson
In the last chapter, we studied the structure of proteins (as well as other biological molecules). In this chapter we will look in detail at one particular kind of protein: the enzyme. The body would not be able to function without enzymes as almost every metabolic reaction that takes place inside the body is catalyzed by an enzyme. Therefore, the study of enzymes is very important in biology. Your knowledge of the general structure of proteins from last chapter will help you as you look at the specific structure of enzymes. In this lesson, you will go very quickly through the whole chapter to get an idea of what you will be learning in the next few lessons.
Preparing for the chapter
- What do you think an enzyme is?
- Why do you think enzymes are important?
- How do you think enzymes work?
First reading of the chapter:
Skim through the chapter quickly (as explained in chapter one)
Second reading of the chapter
Now read the chapter (p.53-71). It is not necessary to take notes as you will work through each section in more detail in the following lessons.
Closing
As you end this lesson, ask yourself:
- What new things have I learned today?
- What did I know already?
- What still confuses me?
NOTE: This chapter cover section 3 of the Cambridge International AS Biology (9700) syllabus 2016-2018 (p.21).
