What is a permeable membrane?

Answer by  Arkana (13)

A permeable membrane is a membrane that allows all ions and molecules to pass, wether by reverse osmosis, or by ion exchange, such as the ion-H+ pump. A permeable membrane can be inside the body, or can also be found in solutions to control the passing of ions and molecules.
