Channel proteins in cell membranes serve what function?
A)They add strength and rigidity to the membrane.
B)They provide pathways for water and electrolytes to move through cell membranes.
C)They form the bilayer portion of the membrane.
D)They allow nonpolar substances to move through the membrane.

Question

Quizplus · Accepted Answer

Channel proteins serve as pathways or channels through which water and electrolytes can move across cell membranes. They do not add strength or rigidity, form the bilayer, allow nonpolar substances to pass, or prevent interactions between nonpolar tails.
