Unit 3: Enzymes And The Digestive System
Name________________________________________
Date____________
block____
Unit Test: Tuesday Oct 25th – 100pts
Corresponding Chapters: Sections 2.3, 2.4, 30.3
Essential Questions:
1. What is a chemical reaction? What is a reactant, what is a product? What do we mean when we
say “chemical reactions rearrange, atoms, but do not destroy them”?
2. Which organic macromolecule are enzymes made out of? What does it mean to be a catalyst?
3. What is an active site? What is a substrate? Why is it important that the enzyme folds properly?
What happens for a chemical reaction if the enzyme does not fold properly?
4. Explain how an enzyme works to catalyze a chemical reaction. Be sure to use the words
“reactant”, “substrate”, “product”, “active site” in your answer.
6. How do pH and temperature affect enzymes? What does it mean for an enzyme to denature?
7. Name the structure and function of all organs of the digestive system. Which organs are of the
alimentary canal? Which organs are “accessory organs”? What does it mean to be an “accessory organ”?
8. Where is salivary amylase made? Where does it function? Which organic macromolecule does it
break down as a reactant, and what is the product?
9. Where is pepsin made? Where does it function? Which organic macromolecule does it break
down as a reactant, and what is the product?
10. Where is bile made? Where is it stored? Where does it function? What does it do?
11. Where are trypsin, pancreatic amylase, and lipase made, and where do all three function? What
does each one do?
12. Explain the difference between a bolus, gastric juice, and acid chyme. What does the sodium
bicarbonate from the pancreas do to the acid chyme that enters in from the stomach?
13. How does the epiglottis help prevent us from choking? What is peristalsis? Why it is important?
What are villi, and why are they important? What would happen if our large intestine didn’t absorb water?
