Quizplus · Accepted Answer

Integral proteins are embedded within the lipid bilayer of the cell membrane, making them inside the membrane rather than being attached to the surface (like peripheral proteins) or freely-floating in the cell's cytoplasm (like globular proteins). Structural proteins do not necessarily occur inside the lipid bilayer and can refer to proteins that help give the cell shape or support, while integral proteins refer specifically to their location within the membrane.
