Which statement correctly describes integral proteins?

Integral membrane proteins are embedded in the lipid bilayer, with portions that interact with the hydrophobic interior. Many of these proteins extend fully across the membrane, spanning from the inside to the outside. This full-span arrangement allows them to function as channels, transporters, or receptors that bridge both sides of the membrane. They are a component of the RBC membrane, not merely attached to the inner surface. Therefore, the best description is that they span the entire thickness of the membrane.
