You need to investigate what enzymes are and how they help you in your day-to-day actions. To brush up on what enzymes are, use the following websites to assist you (make sure to take notes as you go through):

1. What are enzymes and what do they do? What kind of organic compounds are enzymes? Are they beneficial or damaging to your body?

2. How do enzymes work? Use the animations to help you answer the questions.

‘Why enzymes”

1. Describe what you did and how it relates to “building blocks”?

“Specificness”

2. What are the functions of the two enzymes? Why?

“Reusing Enzymes”

3. Write a sentence describing how the words ‘polymer’ and ‘enzymes’ are connected.

“Denaturing”

4. What did the heat do? Why is this important for ‘building blocks’?

5. Now draw, label and explain how enzymes work.

6. You need to understand the 3 main factors (variables) that control the effectiveness of enzyme activity. (The activity that you just did mentioned a few!)

What are the variables?

Variable #1 = ?

Variable #2 = ?

Variable #3 = ?

7. Explain the “lock and key” hypothesis:http://www.coolschool.ca/lor/BI12/unit7/U07L02.htm
