    A specific molecule is able to be transported by facilitated diffusion, which part of the cell membrane would a molecule pass through? - ProProfs

    A specific molecule is able to be transported by facilitated diffusion, which part of the cell membrane would a molecule pass through?

    • A

    • B

    • C

    • 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

    What is the purpose of C? - ProProfs

    What is the purpose of C?

    • It is an area for facilitated diffusion

    • 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.

    • It is an area for osmosis

    • It has no known function.

    Correct Answer
    A. 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

    Which area of the cell membrane is for pumping ions (for example, Sodium and Potassium ions) against the concentration gradient? - ProProfs

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

    • A

    • B

    • D

    • E

    Correct Answer
    A. 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.

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

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

    • A

    • B

    • C

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

    Rate this question:

  • 6. 

    If an animal cell is placed in a hypotonic solution, what will happen?

    • It will shrink when water leaves the cell through osmosis.

    • It will swell as water enters the cell through osmosis.

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

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

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