The small water channels in the cell membrane are called:
A)phospholipid molecules.
B)transport pumps.
C)aquaporins.
D)transport vesicles.

Question

Quizplus · Accepted Answer

Aquaporins are protein channels in the cell membrane that allow the passage of water molecules. They are small and highly selective, only allowing water to pass through and blocking the passage of other molecules. Phospholipid molecules are the main component of the cell membrane, but they do not act as channels. Transport pumps and transport vesicles are involved in transporting molecules across the membrane, but they are not channels for water specifically.
