<prompt> Odorant molecule binds to which receptors?C AMPG protein coupled membrane receptorsJAK kinase pathwayNF receptors  <response>: Ans. is b i.e., G protein coupled membrane receptors Rel Ganong 23de ch 15; Guyton 12he p. 649Odour receptors are G-protein coupled receptors.Receptor-ligand interaction adsorption of odorant molecules to the cilia of receptors results in opening of Na channel through second messenger cAMP.Opening of Na channels result in Na influx and generation of action potentials.
