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 ... WebActive transport: the sodium-potassium pump. Since the plasma membrane of the neuron is highly permeable to K + and slightly permeable to Na +, and since neither of these ions is in a state of equilibrium (Na + being at higher concentration outside the cell than inside and K + at higher concentration inside the cell), then a natural occurrence should …
