Receptors on cell membrane that activate ion channel after binding with agonists are: (A) Nicotonic Cholinergic, (B) Muscarinic Cholinergic, (C) Optoid n receptors, (D) All
Answer is A. 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 receptorReceptorActs'ThroughMuscarinic receptor, opioid andG- protein coupledGABABreceptorMl, M3 (muscarinic)IP3-DAGM2 muscarinic, Opioid 11,6CAMP TIC+, Ca+2,1.GABAB
