Epinephrine activates which receptors
WebMar 5, 2024 · Figure 8.4.8: Protein Kinase A Activation For example, the binding of epinephrine to its receptor on the cell surface, activates, through the action of G-proteins, and subsequent activation of PKA, the phosphorylation of glycogen phosphorylase. WebEpinephrine activates both α and β adrenoceptors and its action on β 2 receptor is more prominent than that of norepinephrine. In smooth muscles, adrenoceptors are predominantly α 1 ( Benschop et al. 1996; Gurrera 1999 ); stimulation of these receptors will lead to vasoconstriction and subsequently elevation of blood pressure ( White et al ...
