Water molecules and small ions enter a cell through
A) transport proteins.
B) receptor proteins.
C) lipid channels.
D) anchor proteins.
E) all of the above

Question

Quizplus · Accepted Answer

Water molecules and small ions cannot pass through the lipid bilayer of the cell membrane due to their hydrophilic nature. Therefore, they require transport proteins to facilitate their movement into the cell. Receptor proteins and anchor proteins do not play a direct role in the movement of water and small ions into the cell. Lipid channels do not exist in the cell membrane.
