Question

Quizplus · Accepted Answer

Increased cAMP concentration activates PKA, which phosphorylates and activates glycogen phosphorylase, leading to increased glycogenolysis.  Increased intracellular cAMP results in the activation of PKA. PKA phosphorylates and activates glycogen synthase-phosphorylase kinase, which will phosphorylate and activate phosphorylase while also phosphorylating and inhibiting glycogen synthase. The increased activity of phosphorylase results in increased release of glucose from glycogen and its subsequent release to the blood.
