<prompt> Receptors on cell membrane that activate ion channel after binding with agonists areNicotonic CholinergicMuscarinic CholinergicOptoid n receptorsAll  <response>: A i.e. Nicotinic cholinergic receptorReceptors with intrinsic ion channelThese cell surface receptors enclose ion selective channels Na, Ca2, CO within their molecule. Agonist binding opens the channels causes depolarization hyperpolarization depending on the ion that flows through.This includes: - Nicotinic cholinergic receptorQ Glutamate receptor Glycine receptor GABAA receptorQ - 5HT3 receptorReceptorActsThroughMuscarinic receptor, opioid andG- protein coupledGABABreceptorMl, M3 muscarinicIP3-DAGM2 muscarinic, Opioid 11,6CAMP TIC, Ca2,1.GABAB
