2. 1 – 6 pts
What is another word for Passive Transport?
Diffusion

3. 1 – 7pts
When water does diffusion, it’s called
Osmosis

4. 1 – 8 pts
Describe how molecules move in the process of Diffusion and Osmosis
Move from areas of high to low concentration.

5. 1 – 9 pts
Give one example of diffusion or osmosis that occurs in the body.
Digested nutrients diffuse from small intestines into the villi (blood stream).
Water diffuses from feces into the walls of the large intestines.

6. 1 – 10 pts Why must food be digested (broken down)?
It must be small enough to enter the cell membrane of cells.

7. 2 – 6 pts
The nutrient starch is digested into...
Glucose (sugar)

8. 2 – 7 pts
Lipids are digested into…
Fatty Acids and glycerol

9. 2 – 8 pts
Proteins are digested into…
Amino acids

10. 2 – 9 pts
Special proteins in the digestive tract that help speed up digestion are known as:
Enzymes

11. 2 – 10 pts
The digestion of starch starts in the ________ and ends in the __________.
Mouth…….small intestines.

12. 3 – 6 pts
Stomach acid has a PH of about….
1- 2

13. 3 – 7 pts Why doesn’t gastric acid destroy the stomach?
A mucus membrane protects the wall of the stomach.

14. 3 – 8 pts
What is the name of the following structure and where is it found?
Villi are found in the walls of the small intestines.

15. 3 – 9 pts Why are villi shaped like finger-like extensions?
It has more surface area for food to diffuse through into the blood stream.

16. 3 – 10 pts What is the function of bile juice in the small intestines?
To break up large chunks of fat into little droplets of fat.

17. 4 – 6 pts Where is bile made and stored?
It is made in the liver and stored in the gall bladder.

18. 4 – 7 pts
Describe one function of the Pancreas in the Digestive System.
It releases digestive enzymes in the small intestines.
It releases antacid (base) into the small intestines to neutralize the stomach acid.

19. 4 – 8 pts

Appendix

20. 4 – 9 pts
The rhythmic pushing of food from the mouth to the large intestines is called:
Peristalsis

21. 4 – 10 pts

Diarrhea

22. 5 – 6 pts
What does the following graph tells us about enzymes in the human body.
Enzymes work best at a 40 deg Celcius

23. 5 – 7 pts
If a person has their gall bladder removed, how must they change their diet.
They can not eat a large amount of fats in one sitting.

24. 5 – 8 pts
Why can diffusion happen in a dead leaf, but not active transport?
Active Transport requires ATP energy

25. 5 – 9 pts Describe why starch enzymes will not work on proteins?
Enzymes must fit into the molecule it is changing

26. 5 – 10 pts
What does our body do with the amino acids it digested and absorbed?
Synthesizes our bodies proteins.
