Red blood cells have a higher proportion of aquaporins on the membrane than skin cells do.Assuming equal osmotic pressures,which is true?

Question

Quizplus · Accepted Answer

Aquaporins are water-specific channels that allow for the rapid movement of water molecules across cell membranes. As red blood cells have a higher proportion of aquaporins on their membrane than skin cells, water will move faster across the red blood cell membrane (i.e. osmosis will occur faster) than across the skin cell membrane. Thus, B is the correct answer.

Red Blood Cells Have a Higher Proportion of Aquaporins on the Membrane
