Multiple Choice

Carbohydrates attach to which two types on the outer surface of the plasma membrane?

Carbohydrates on the cell’s outer surface are covalently attached to lipids and proteins, forming glycolipids and glycoproteins that protrude into the extracellular space. This outer decoration helps with cell recognition, signaling, and interactions with the environment. They are not attached to nucleic acids, and they’re not limited to the inner surface. So the two groups that carry these carbohydrate chains on the outside are lipids and proteins.
