Ion channel and transporter
WebIon channels and transporters share common 3D space on the surface of cells and within the plasma membrane, and recent evi-dence points toward physical and functional … WebThere are three members of the family of ligand-gated receptors, namely NACHR, GABAAR and glycine receptors. Such receptors have the dual role of receptors and ion channels. Unlike pre-receptors, they are composed of multiple subunits. These subunits form a ion channel. The neurotransmitter binds to the receptor, alters the conformation of the ...

WebIon channels are “passive” transporters, they never use ATP, just dissipate/disperse gradients that already exist. We will return to this in more detail with the discussion of the action potential.
