Explanation:
Detailed explanation-1: -The channels are opened, or gated, by the binding of a neurotransmitter to an orthosteric site(s) that triggers a conformational change that results in the conducting state. Modulation of gating can occur by the binding of endogenous, or exogenous, modulators to allosteric sites.
Detailed explanation-2: -Voltage channels open and close in response to changes in membrane potential. Mechanically-gated channels open in response to physical deformation of the receptor, as in sensory receptors of touch and pressure.
