Question

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?

Answer 1

Water molecules will still be able to move across the cell membrane but at a slower rate.

Step-by-step explanation:

The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

Answer 2

Water molecules will still be able to move across the cell membrane but at a slower rate.

Step-by-step explanation:

D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
