Question

The drawing below shows a portion of the cell membrane and all of the molecules that comprise it.

The lipid bilayer molecules do what for the cell?

A. help cells recognize each other
B. allow food molecules into the cell
C. prevent the passage of certain molecules into the cell
D. organize amino acids for protein synthesis

Answer 1

C. prevent the passage of certain molecules into the cell

Answer 2

Prevent the passage of certain molecules into the cell.

Step-by-step explanation:

Cell membrane or plasma membrane consists of lipid bilayer in which proteins are embedded. The carbohydrates are present in the plasma membrane in association with lipids and proteins.

The cell membrane acts as the semi-permeable membrane that allows the movement of selected particles into and out of the cell. The molecules may enter through diffusion, osmosis or by active transport depending on the tyep of molecule.

Thus, the correct answer is option (C).
