If cells that normally contain aquaporins undergo a mutation that destroys aquaporin function, which outcome can be expected?
A) The cells will experience uncontrollable water loss.
B) The cells will experience uncontrollable sodium and potassium ion uptake.
C) The cells will lose the ability to take up or release sodium and potassium ions.
D) The cells' membranes will become impermeable to water.
E) The cells will have no means for any polar compounds to diffuse across their membranes.

Question

Quizplus · Accepted Answer

Aquaporins are membrane proteins that facilitate the movement of water across cell membranes. If these proteins are destroyed or non-functional, the cells will not be able to regulate the movement of water, leading to an inability to retain water and ultimately dehydration. The cells' membranes will become impermeable to water, as they will have no mechanism to transport water across the membrane.
