Final answer:
Glycolipids are found exclusively on the outer surface of the cell membrane, acting as surface markers for the cell and serving in cellular recognition and cell-to-cell communication.
Step-by-step explanation:
Glycolipids are chains of carbohydrates attached directly to a lipid in the membrane. They are found exclusively on the outer surface of the cell membrane, acting as distinguishing surface markers for the cell and serving in cellular recognition and cell-to-cell communication.
On the other hand, intracellularly, filaments of the cytoskeleton provide scaffolding for the membrane.
Therefore, glycolipids are found on the outside leaflet of the membrane.
