Cell Membrane, Cell Transport and Cell Processes – Study Guide
This study guide is to help you understand and recall all the concepts that will be included on the test.
Please be aware that it is not to be used as a replacement for studying your notes and labs. It is only
to be used as a supplement.
The Cell Membrane
1. Label the carbohydrate chain, lipid bilayer – hydrophobic, lipid bilayer – hydrophilic, and the
protein channel in the cell membrane illustration.
2. What is the function of the cell membrane?
3. How does the lipid bilayer stop large molecules from passing through the cell membrane?
4. How does the lipid bilayer stop charged molecules from passing through the cell membrane?
5. Give an example of a large molecule. Give an example of a charged molecule. Give an example
of a small, uncharged molecule.
i.
Large: _________________________
ii.
Charged: _______________________
iii.
Small, Uncharged: ___________________
6. Water is polar. What specialized protein channels allow the diffusion of water?
Cell Transport
7. What is passive transport? What are two examples of passive transport?
8. Someone in the kitchen is baking cookies. Why can you smell them from your room?
9. Define diffusion and give one example.
10. Using the picture below answer the following questions:
11. What type of solution is the cell in (hypertonic, hypotonic, or
isotonic)?
12. The solutes are charged and cannot diffuse. Which way will
the water diffuse?
13. What will the cell look like after 24 hours?
14. You place your egg into tap water which 99% water. The egg is 76% water and 23% solutes.
Draw a picture to help you answer the following questions.
i.
Is the solution hypotonic, hypertonic, or isotonic?
ii.
What happens to the cell?
15. You place a leaf in a 20% salt solution (much more salt than a leaf normally contains). Explain
what happens to the plant’s cells in this solution. What type of solution is the salt solution?
16. What is active transport? When is active transport used?
17. Give three types of active transport.
i.
_____________________________
ii.
_____________________________
iii.
_____________________________
18. How do Endocytosis and Exocytosis differ?
19. Describe how energy is used in protein pumps.
20. What are two differences between active and passive transport?
i.
ii.
21. What is one similarity between active and passive transport?
Energy
22. What molecule is used directly for energy in living organisms?
23. The energy from our ____________________ is converted into _________ (the molecule used for
energy directly) and used in the body for cellular processes.
24. How is energy stored in ATP?
25. How is energy released in ATP?
26. Why doesn’t the body store ATP instead of lipids/carbohydrates?
Photosynthesis
27. What is the function (purpose) of photosynthesis?
28. What substances are needed in order for photosynthesis to occur?
29. What is produced from photosynthesis?
30. Where in the cell does photosynthesis take place?
31. What is photosynthesis role in the carbon cycle?
32. The green coloration in plants is the result of plants _________________ (absorbing/reflecting)
green light waves.
Respiration
33. What is the function (purpose) of respiration?
34. What substances are needed in order for respiration to occur?
35. What is produced from respiration?
36. What are the two types of respiration? What are three ways differ?
i.
Type A: _____________________________
ii.
Type B: _____________________________
iii.
Differences:
37. What is respirations role in the carbon cycle?
38. How is respiration and photosynthesis related?
