1. Starter: List three
things you know
about enzymes.
Enzymes

2. Enzymes
WALT: To be able to describe the role of enzymes.
WILF:
~ Recall that enzymes are a protein. (D)
~ Describe how enzymes catalyse reactions without being
used up themselves. (C)
~ Describe the role of particular examples of enzymes both
inside and outside cells. (B)
~ Explain the importance of enzymes and how they are
specific to different reactions. (A/A*)
Keywords
enzyme digestion catalyst

3. What are enzymes?
Enzymes are
proteins.
They help to carry out
chemical reactions in
the body.
They are catalysts.
They are specific.
Globular shaped
protein

4. What are enzymes?
What is the function
of enzymes?
Describe what the
word catalyst means.
Explain why enzymes
are specific.
Globular shaped
protein

5. Enzymes inside cells Enzymes outside
cells

6. Microorganisms and fungi
also use digestive
enzymes to digest foodsaprophytic feeding.

7. Enzymes and dirty socks!
Biological detergents contain
enzymes.
These enzymes catalyse the
breakdown of some of the
substances found in stains on dirty
clothes.
You are going to compare the cleaning
power of a biological detergent with a
non-biological detergent, to see what
effect the enzymes have.
