The pancreas produces the hormone glucagon, which plays a key role in regulating blood glucose concentration. Select the statement that incorrectly describes the action of glucagon:
It binds to specific receptors on the cell surface membrane of hepatocytes.
It activates enzymes that catalyse the condensation of glucose to form glycogen.
It activates adenylate cyclase, which leads to the formation of cyclic AMP (cAMP\text{cAMP}cAMP).
It stimulates the conversion of non-carbohydrates, such as glycerol and amino acids, into glucose.
