Question

Quizplus · Accepted Answer

Ligand-gated channels are also known as ionotropic receptors. These membrane channels open in response to the binding of specific chemicals or ligands, such as neurotransmitters, hormones, or drugs, to their binding sites on the receptor protein. When the ligand binds, the channel gate is triggered to open, allowing ions to flow into or out of the cell, thus producing electrical signals. Ligand-gated channels are found in various tissues and cells, including the dendrites of some sensory receptors like pain receptors and in the dendrites and cell bodies of interneurons and motor neurons.
