Which of the following is NOT a function of the cytoplasmic membrane?

a Permeability barrier

b Energy conservation and production

c Anchor for proteins

d Determines cell shape and size

Solution

Answer is b. Energy conservation and production is not a function of the cytoplasmic membrane.

Cytoplasmic membrane is also called as plasma membrane or cell membrane.

Cytoplasmic membrane is an lipid bilayered structure and it is embedded with the proteins. It is a membrane that separates the interior cells from outside environment.

FUNCTIONS OF CYTOPLASMIC MEMBRANE :

Main function of cell membrane is to protect the cell from its surrounding membrane.

Cytoplasmic membrane is a selectively permeable membrane that means it allows only some selected ions and organic molecules and controls the movement of substances in and out of the cells.

Cell membrane provides the shape to the cell and it holds all the cells together to form tissues. It provides mechanical support to the cell.

The cell membrane maintains the cell potential by the passage of certain molecules in and out and the passage of molecules generally occurs through transport mechanisms.
