Rise in blood glucose levels / Fall in blood glucose levels / β cells release insulin which travels in the blood
Detected by α cells in the islets of Langerhans in the pancreas / Glucagon binds to specific target cells / receptors on the liver cell membranes / An enzyme converts glycogen to glucose (glycogenolysis)
This lowers the glucose concentration in the blood / Detected by β cells in the islets of Langerhans in the pancreas / Also, an enzyme converts glucose to glycogen (glycogenesis)
The membrane of liver and muscle cells become more permeable to glucose, so glucose is absorbed / Also, glucagon promotes the formation of new glucose (gluconeogenesis) from fatty acids and amino acids / Insulin binds to specific target cells / receptors on the liver and muscle cell membranes
This raises the glucose concentration in the blood / α cells release glucagon which travels in the blood
