All of the Following Can Be a Constituent of a Cell

Question

All of the following can be a constituent of a cell membrane, except:
A) phospholipids.
B) glycolipids.
C) glycoproteins.
D) messenger RNA.
E) cholesterol.

Accepted Answer

Messenger RNA (mRNA) is not a component of the cell membrane. The cell membrane is primarily composed of phospholipids, glycolipids, glycoproteins, and cholesterol, which are involved in the structure and function of the membrane, such as fluidity and signaling. mRNA, on the other hand, is involved in the process of protein synthesis and does not play a direct role in the structure or function of the cell membrane.
