stimulation of B2 receptor produce
Answers
Explanation:
Beta-2 adrenoceptors are activated by the catecholamines norepinephrine and epinephrine, and are members of the adrenoceptor family of the 7-transmembrane superfamily of receptors. There are three beta adrenoceptor subtypes: beta-1, beta-2, and beta-3. The beta-2 adrenoceptor is the prototypical G protein-coupled receptor and much is known about its structure, function, and regulation. Selective beta-2 agonists include salbutamol, terbutaline, and salmeterol. Beta-2 adrenoceptors are implicated in diverse physiological functions in the body, especially in the pulmonary system and cardiovascular systems. Activation of adenylate cyclase through Gs is the classic, but not the only, mechanism of beta-2 adrenoceptor action.The beta-2 adrenoceptor has been the prototypical receptor for studying the desensitization, internalization, and down-regulation of receptors …
