Read each question carefully and provide your best answer. For multiple-choice questions, circle the letter corresponding to the correct answer. For fill-in-the-blank and short-answer questions, write your answer in the space provided.
1. Which type of transport does NOT require energy to move substances across the cell membrane?
Active transport
Passive transport
Endocytosis
Exocytosis
2. The movement of water across a selectively permeable membrane from a region of higher water concentration to a region of lower water concentration is called:
Diffusion
Facilitated diffusion
Osmosis
Active transport
3. The cell membrane is primarily composed of a bilayer.
4. In , carrier proteins are used to move substances down their concentration gradient without the use of ATP.
5. A solution with a higher concentration of solutes than the cell's cytoplasm is called a solution.
6. Active transport moves substances from an area of low concentration to an area of high concentration.
True
False
7. The sodium-potassium pump is an example of passive transport.
True
False
8. Describe the primary difference between diffusion and osmosis.
9. Explain how the structure of the cell membrane contributes to its function in regulating cellular transport.
10. Label the following components on the diagram of the cell membrane:
a. Phospholipid bilayer
b. Integral protein
c. Glycoprotein
