Final answer:

A lipid-anchored protein is the type of membrane protein that is found entirely outside the bilayer and covalently linked to a membrane lipid within the bilayer.

Step-by-step explanation:

The type of membrane protein that is found entirely outside the bilayer on either the extracellular or cytoplasmic surface and is covalently linked to a membrane lipid situated within the bilayer is a lipid-anchored protein. These proteins are not embedded in the membrane like integral proteins or loosely associated with the surface like peripheral proteins. Instead, they are attached to a membrane lipid within the bilayer.

Lipid-anchored proteins are the type of membrane proteins that are located entirely outside the bilayer and covalently linked to a membrane lipid within the bilayer.

The type of membrane protein found entirely outside the bilayer on either the extracellular or cytoplasmic surface and that are covalently linked to a membrane lipid within the bilayer are known as lipid-anchored proteins. These proteins are not considered integral because they do not span across the membrane, nor are they peripheral proteins as they are covalently bound rather than associated through non-covalent interactions. They perform various functions for the cell, including signaling and maintaining the structural integrity of the cell.
