Which of the following is True of integral membrane proteins?
A)They lack tertiary structure.
B)They are loosely bound to the surface of the bilayer.
C)They are usually transmembrane proteins.
D)They are not mobile within the bilayer.
E)They serve only a structural role in membranes.

Question

Quizplus · Accepted Answer

Integral membrane proteins are usually transmembrane proteins, meaning they span the entire lipid bilayer. This allows them to interact with both the intracellular and extracellular environments. They have a tertiary structure and are tightly bound to the surface of the bilayer. They are also mobile within the bilayer, allowing for dynamic interactions with other membrane components. Integral membrane proteins serve a variety of functions, including transport, signal transduction, and enzymatic activity.
