Ion transport is the movement of ions across a membrane, passively through ion channels or actively through ion pumps such as symporters and antiporters. Animal toxins can modulate action ...

Ion channels are integral membrane protein assemblies that modulate the flow of ions into and out of a cell or organelle, leading to generation of electrical signals. Opening (gating) of ion ...
