Question

What kind of membrane protein is found entirely outside the bilayer on either the extracellular or cytoplasmic surface? these proteins are covalently linked to a membrane lipid situated within the bilayer?

Answer 1

they are peripheral proteins

Answer 2

Peripheral protein are membrane proteins is found entirely outside the bilayer on either the extracellular or cytoplasmic surface.

Lipid linked proteins are covalently linked to a membrane lipid situated within the bilayer.

What are the 4 types of membrane proteins?

Integral proteins come in different types, such as monotopic, bitopic, polytopic, and lipid-anchored proteins. Monotopic integral proteins are only attached to one of the cell's two leaflets. Bitopic integral proteins are transmembrane proteins that can span lipid bilayers once.

Thus, Peripheral protein and Lipid linked proteins are correct.
