Ligand gated channels are also called as ionotropic receptors that open in response to the binding of specific ion, which is generally not solute. These are made up of particular set of transmembrane proteins that open and close to allow the movement of ions like K+, Na+ that passes through the plasma membrane in response to binding of the chemical messenger.
Explanation: Endoplasmic reticulum serves as channels for the transport of materials between various regions of the cytoplasm or between the cytoplasm and the nucleus.
