WitrynaBeta-1 adrenoceptors are G s coupled receptors that stimulate adenylyl cyclase [AC] increasing the production of the second messenger cAMP. Most notably, beta-1 stimulation results in stimulation of the heart with a positive chronotropic and inotropic effects because these receptors are primarily located in the heart.

The mechanism of adrenoreceptors. Adrenaline or noradrenaline are receptor ligands to either α1, α2 or β-adrenoreceptors. α1 couples to Gq, which results in increased intracellular Ca and subsequent smooth muscle contraction. α2, on the other hand, couples to Gi, which causes a decrease in neurotransmitter release, as well as a decrease of cAMP activity resulting in smooth muscle contraction. …
