Question

How does presence of aquaporins affect osmosis?

Answer 1

Aquaporins are "the plumbing system for cells". ... Aquaporins selectively conduct water molecules in and out of the cell, while preventing the passage of ions and other solutes. Also known as water channels, aquaporins are integral membrane pore proteins.

Answer 2

Aquaporins are special channels which transports the water in and out of the biological membrane. The presence of aquaporins accounts for the most of the water transport than by simple diffusion. Water passes quickly in the presence of aquaporins than by the osmosis.
