Final answer:
Glycoproteins are located on the outside of the membrane and function in cell recognition and identification. They have carbohydrate oligomers attached to the outer lipid layer, allowing cells to interact with the external environment.
Step-by-step explanation:
Glycoproteins are located on the outside of the membrane and function in cell recognition and identification. They have carbohydrate oligomers attached to the outer lipid layer, allowing cells to interact with the external environment. Glycoproteins aid in cell-to-cell recognition and play a crucial role in the immune system's ability to distinguish between self and non-self cells.
