Question

the movement of water molecules from high concentration to low concentration (through aquaporins) is called:
□ osmosis
□ endocytosis
□ sodium - potassium pump
□ facilitated diffusion

Explanation:

Osmosis is the movement of water molecules from an area of high water - concentration to an area of low water - concentration across a semi - permeable membrane (such as through aquaporins). Endocytosis is the process of taking substances into the cell by forming vesicles. The sodium - potassium pump is involved in active transport of sodium and potassium ions. Facilitated diffusion is the movement of molecules across the membrane with the help of transport proteins, but not specifically for water movement through aquaporins in the context of the given definition.

Answer:

A. osmosis
