Which proteins are located on the inner or outer surface of the plasma membrane, usually bound to exposed regions of integral proteins by noncovalent interactions?

A) Plasma membrane proteins
B) Biological membrane proteins
C) Transmembrane proteins
D) Peripheral membrane proteins
E) Integral membrane proteins

Peripheral Membrane Proteins

Proteins that are attached either temporarily or permanently to the outer or inner surface of the cellular membrane, often involved in signaling or structural roles.

Integral Proteins

Proteins that are permanently attached to or span the membrane of cells, playing crucial roles in transport and signaling.

Plasma Membrane

The lipid bilayer membrane that encases a cell, providing structural support, protection, and the ability to communicate with the external environment.
