Aquaporins are channels that allow to travel across plasma membranes.

Which of these molecules is correctly matched with its method of movement through the cell membrane?Multiple ChoiceGlucose and amino acid molecules — pass through membrane channels.Large, water-soluble molecules — transported by carrier-mediated processes.All of the choices are correctly paired.Lipid-soluble molecules — pass through membrane channels.Small, water-soluble molecules (ions) — dissolve in double phospholipid layer.
