Odorant molecule binds to which receptors?
G protein coupled membrane receptors
JAK kinase pathway
Ans. is ‘b’ i.e., G protein coupled membrane receptors
- Odour 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.
