Stimulation of beta 1 receptors
WebBeta receptors are composed of three main categories, beta-1, beta-2 and beta-3, and are located in various organs and tissues (see below). All subtypes of beta adrenoceptors are … WebBeta-1 adrenoceptors are Gs 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.
