Parts Of A Cell Membrane - Quiz

Parts of a cell membrane and movement through the membrane.


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

    Correct Answer
    A. A
    Explanation
    Facilitated diffusion: No energy needed, but can not fit through the phospholipid bilayer. It needs to go through the protein channels. A is a protein channel. IMPORTANT: DIFFERENT SUBSTANCES NEED TO GO THROUGH DIFFERENT CHANNELS

    Rate this question:

  • 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.

    Correct Answer
    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.
    Explanation
    Carbohydrate "marker" : Identifies cells

  • 3. 

    What part of the cell is for transport of very small particles - without energy needed:?

    • A.

      A

    • B.

      B

    • C.

      C

    Correct Answer
    B. B
    Explanation
    Very small particles can diffuse (no energy) through the phospholipid bilayer.

    Rate this question:

  • 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

    Correct Answer
    D. E
    Explanation
    A pump is used to move substances (example: ions) against the concentration gradient (low to high). It can be distinguished in this picture by the presence of ATP. ATP is the molecule used by the cell for energy.

  • 5. 

    What part of the cell membrane is hydrophobic?

    • A.

      D

    • B.

      E

    Correct Answer
    A. D
    Explanation
    The phospholipid "tails" are hydrophobic - they are "hiding" (phobic = afraid) away from the watery environment of the cell.

    Rate this question:

  • 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.

    Correct Answer
    B. It will swell as water enters the cell through osmosis.
    Explanation
    A cell SWELLS (like a HIPPO) in a HYPOtonic solution.
