1. Review all of the information on the Macromolecule Review Sheet & Quiz
2. Study your Digestive System Chart. You need to know the function of each digestive organ, and what type of
digestion it takes part in (Mechanical, Chemical, or both)
3. What is the difference between the Gastrointestinal (GI) Tract and the Accessory Digestive Organs?
4. What is the path that food takes through the Gastrointestinal (GI) Tract? List these GI organs in the order in
which food will travel, from beginning to end.
5. List all of the organs (GI and Accessory) that are involved in chemical digestion (There should be 6):
6. List all of the organs that are involved in mechanical digestion (There should be 2):
7. List all organs that do not actually digest food, but serve as a pathway for food to travel (There should be 5):
8. Which organ in the GI Tract is responsible for absorbing the nutrients from the food that’s being digested?
Explain what happens after they’re absorbed here:
9. Label #’s 1-11 on the Digestive System Diagram below:

Review how to read a nutrition label. Serving size, calories, fat, etc.

What is an enzyme? Relate the terms enzyme and catalyst to one another.

Write a short paragraph linking the following terms together: enzyme, catalyst, active site,
substrate, product, lock and key, activation energy.

Think about the yeast sphere lab that we did.
1. Identify the reaction that the yeast is speeding up.
2. What is the enzyme being produced by yeast?
3. What is/are the substrate(s), what is/are the product(s) of the reaction?
4. Explain why the yeast spheres floated to the top of the hydrogen peroxide solution.
5. Explain the results of the concentration of hydrogen peroxide lab- how did the speed of the reaction
relate to the concentration of the substrate?
6. Can you explain your temperature results?
