Detailed explanation-1: -Which of the following is true regarding ligand-gated ion channels? Explanation: Ligand-gated ion channels are activated by a ligand. Upon activation, the ion channels open and allow for passage of ions through the membrane.

Detailed explanation-2: -01) Which of the following statements is not true about a ligand gated ion channel receptor? Feedback: Ligand gated ion channels consist of five glycoproteins and not six. The other statements are correct. Receptors that are controlled by the membrane potential are known as voltage gated ion channels.

Detailed explanation-3: -Ligand-gated ion channels bind neurotransmitters and open in response to ligand binding. These channels control synaptic transmission between two neurons or between a neuron and a muscle.

Detailed explanation-4: -The ligand-gated ion channel superfamily includes nicotinic acetylcholine receptors (nAChRs), adenosine triphosphate (ATP) receptors, -aminobutyric acid (GABA), glutamate, glycine, and 5-hydroxytryptamine (5-HT) receptors (Dent, 2010).
