The fluidity of membranes in a plant in cold weather may be maintained by

A. increasing the number of phospholipids with unsaturated hydrocarbon tails.

B. increasing the proportion of integral proteins.

C. increasing concentration of cholesterol in membrane.

D. increasing the number of phospholipids with saturated hydrocarbon tail.

Correct Answer : A.


The concept of membrane fluidity refer to the fact that both lipids and proteins may have considerable freedom of lateral movements within the bilayer. The fluidity of membranes in a plant in cold weather may be maintained by increasing the number of phospholipids with unsaturated hydrocarbon tails.
