Questions and Answers
  • 1. 
    A specific molecule is able to be transported by facilitated diffusion, which part of the cell membrane would a molecule pass through?
    • A. 

      A

    • B. 

      B

    • C. 

      C

    • D. 

      D

  • 2. 
    What is the purpose of C?
    • A. 

      It is an area for facilitated diffusion

    • B. 

      It is an identity marker for the cell. For example, each cell of the human body as a marker, so the immune system can tell self from non-self.

    • C. 

      It is an area for osmosis

    • D. 

      It has no known function.

  • 3.

    • A. 

      A

    • B. 

      B

    • C. 

      C

  • 4. 
    Which area of the cell membrane is for pumping ions (for example, Sodium and Potassium ions) against the concentration gradient?
    • A. 

      A

    • B. 

      B

    • C. 

      D

    • D. 

      E

  • 5. 
    What part of the cell membrane is hydrophobic?
    • A. 

      D

    • B. 

      E

  • 6. 
    If an animal cell is placed in a hypotonic solution, what will happen?
    • A. 

      It will shrink when water leaves the cell through osmosis.

    • B. 

      It will swell as water enters the cell through osmosis.

    • C. 

      It will stay the same size, no activity will happen.

    • D. 

      It may burst or shrink, it depends on the temperature.
