The figure shows a transmembrane protein that spans the entire lipid bilayer of the membrane. This type of protein is known as an integral membrane protein. Peripheral membrane proteins attach to the surface of the membrane while integral proteins extend through the hydrophobic region of the membrane. Therefore, integral is the best choice to describe the type of membrane protein in the figure.
