Which Statement is NOT True of the Organic Molecules of Cell

Question

Which statement is NOT true of the organic molecules of cell membranes?
A)Cholesterol forms carrier molecules.
B)Proteins form receptors.
C)Phospholipids make up the bilayer of the membrane.
D)Oligosaccharides are self antigens.

Accepted Answer

Cholesterol is one of the components of the cell membrane, but it does not form carrier molecules. It helps to maintain the fluidity and stability of the membrane. Oligosaccharides are also present in the membrane and are involved in cell recognition and communication. Therefore, option D is also incorrect. Proteins form integral and peripheral components of the membrane, and they serve various functions such as channels, pumps, receptors, and enzymes. Phospholipids are the main structural components of the membrane and form the lipid bilayer.
