After a carbohydrate-rich meal, the rising level of blood glucose promotes Beta cells of the pancreas secreting the hormone insulin into the blood. Insulin triggers the uptake of glucose from the blood into body cells, and stimulates the liver to store glucose as glycogen.

Explain how the antagonisc hormones insulin and glucagon regulate
carbohydrate metabolism.
• After a carbohydrate-rich meal, the rising level of blood glucose promotes Beta cells of
the pancreas secreting the hormone insulin into the blood. Insulin triggers the uptake
of
glucose from the blood into body cells, and stimulates the liver to store glucose
as glycogen.
• After fasting, when blood in the hepatic portal vein has a much lower glucose
concentration, Alpha cells of the pancreas secrete the hormone glucagon into the
blood. Glucagon stimulates the liver to break down glycogen, convert amino acids and
glycerol to glucose, and release glucose into the blood.
