The Passive Process That Involves the Movement of Water Through

Question

The passive process that involves the movement of water through aquaporins is ________.
A) facilitated diffusion
B) endocytosis
C) solute pumping
D) osmosis

Accepted Answer

Aquaporins are pore-forming transmembrane proteins that allow the passive movement of water molecules across the cellular membrane by the process of osmosis. Facilitated diffusion refers to the facilitated movement of molecules across the membrane with the help of proteins, endocytosis refers to the active process of engulfing the molecules into the cell, and solute pumping refers to the active process of moving molecules against the concentration gradient.
