Quizplus · Accepted Answer

Membrane proteins perform various functions including facilitating the transport of molecules across the membrane, acting as enzymes to speed up chemical reactions, and serving as receptors for detecting chemical signals. Options A, B, D, and E include functions not directly performed by membrane proteins or attribute to them roles that are more accurately described as properties of the membrane itself (e.g., providing a relatively impermeable bilayer structure or regulating membrane fluidity).
