4. Try Again.
Back to question 1.

5. Question 2
Which section shows active transport? Section I Section II Section III

6. That’s Correct!
Section III represents active transport. Go to question 3.

7. Try Again.
Back to question 2.

8. Question 3
Which section represents diffusion? Section I Section II Section III

9. That’s Correct!
Section I represents diffusion. Go to question 4.

10. Try again.
Back to question 3.

11. Question 4
Which section(s) are considered passive transport? Section I only Sections I and II Sections II and III

12. That’s Correct!
Sections I and II are considered passive transport. Go to question 5.

13. Try again.
Back to question 4.

14. Question 5
Why are sections I and II considered passive transport? Molecules move from high to low concentration Energy is used to transport molecules Molecules move from low to high concentration

15. That’s Correct!
Molecules move from high to low concentration in sections I and II. Go to question 6.

16. Try again.
Back to question 5.

17. Question 6
A solution of 1 M glucose is separated by a selectively permeable membrane from a solution of 0.2 M. The membrane is not permeable to the sugar molecules. Which side is initially hypertonic? Side A Side B Sides A and B

18. That’s Correct!
Side A is initially hypertonic. Side A contains more solute than side B. Go to question 7.

19. Try again.
Back to question 6.

20. Question 7
What is the direction of osmosis in the diagram? There is no net movement of water Water moves from side A to side B Water moves from side B to side A

21. That’s Correct!
Water moves from side B to side A. The direction of osmosis moves from the hypotonic side (less solute/more water) to the hypertonic side (more solute/less water). Go to question 8.

22. Try again.
Back to question 7.

23. Question 8
An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane has just been immersed in a beaker containing a different solution. The membrane is permeable to water and to the simple sugars glucose and fructose but completely impermeable to the disaccharide sucrose.
Which solute(s) will exhibit a net diffusion into the cell?
Sucrose
Glucose
Fructose
Glucose and fructose

24. That’s Correct!
Fructose will diffuse into the cell. Go to question 9.

25. Try again.
Back to question 8.

26. Question 9
An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane has just been immersed in a beaker containing a different solution. The membrane is permeable to water and to the simple sugars glucose and fructose but completely impermeable to the disaccharide sucrose.
Which solutes(s) will exhibit a net diffusion out of the cell?
Sucrose
Glucose
Sucrose and Glucose

27. That’s Correct!
Glucose will diffuse out of the cell. Go to question 10.

28. Try again.
Back to question 9.

29. Question 10
Is the solution outside the cell isotonic, hypotonic, or hypertonic? Isotonic Hypotonic Hypertonic

30. That’s Correct!
The solution on the outside of the cell is hypotonic. Go to reference.

31. Try again.
Back to question 10.
