Final answer:
The major regulatory hormone of the postabsorptive state is glucagon. Glucagon is released from the pancreas in response to a drop in blood glucose levels and acts on the liver to break down stored glycogen into glucose. liver cells, inhibiting the synthesis of glycogen and stimulating the breakdown.
Step-by-step explanation:
The major regulatory hormone of the postabsorptive state is glucagon. During the postabsorptive state, when the body is fasting and glucose levels in the blood drop, glucagon is released from the alpha cells of the pancreas. Glucagon acts upon the liver cells, inhibiting the synthesis of glycogen and stimulating the breakdown of stored glycogen into glucose, which is then released into the blood.
