One function of integral membrane proteins in the plasma membrane of cells is to form channels to allow passage of nonpolar solutes into the cell.

Question

Quizplus · Accepted Answer

Integral membrane proteins can form channels for the selective passage of specific polar solutes, such as ions and water molecules, but they do not facilitate the transport of nonpolar solutes into the cell. Nonpolar solutes can diffuse across the lipid bilayer without the need for specific transport proteins.
