Question

Choose the correct answer from the alternatives given.
Which of the following function does the lipid bilayer component of the cell membrane not provide for the cell?

• A. Controls the exchange of matter and chemical information between one cell and adjacent cells or the environment
• B. Provides an impermeable, self-sealing membrane capable of dividing or fusing the cell without breaking
• C. Provides the matrix into which proteins are inserted that facilitate the exchange of matter between the inside and outside of the cell
• D. Clearly defines a boundary preventing an equilibrium between the outside and inside of the cell

Answer 1

The correct option is B Provides an impermeable, self-sealing membrane capable of dividing or fusing the cell without breaking

The lipid bilayer of the cell membrane does not completely isolate the cell from its surrounding instead, it is a semipermeable membrane with pores and receptors that allows a selective exchange of material and information between the environment inside and the outside the cell.

So, the correct answer is 'Provides an impermeable, self-sealing membrane capable of dividing or fusing the cell without breaking'.
