Detailed explanation-1: -Epinephrine and Norepinephrine Like the glucagon receptor, -adrenergic receptors are linked to a Gs signaling pathway that increases intracellular cAMP. Epinephrine also promotes glycogenolysis and gluconeogenesis through the 1 adrenergic receptor, which is coupled to the Gq/IP3/DAG signaling pathway.
Detailed explanation-2: -Definition: A G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation of adenylyl cyclase activity and a subsequent increase in the intracellular concentration of cyclic AMP (cAMP).
Detailed explanation-3: -When epinephrine binds to its receptor on a muscle cell (a type of G protein-coupled receptor), it triggers a signal transduction cascade involving production of the second messenger molecule cyclic AMP (cAMP).
