Quizplus · Accepted Answer

Epinephrine binding to its receptor activates adenylate cyclase through a G protein-coupled receptor mechanism, leading to an increase in cyclic AMP (cAMP) levels in the cytosol. This signaling pathway is involved in the mobilization of energy stores, among other effects.
