The insulin:glucagon, or I:G ratio, is important and variable. The balancing act between insulin and glucagon maintains the blood glucose level for supplying the brain, matches the nutrient supply to the immediate needs of the body’s tissues, and stores the surplus. Insulin takes precedence to facilitate the uptake and storage of nutrients when they flood into the blood after digestion of a meal, so the I:G ratio is high. Glucagon promotes the release of glucose and fatty acids into the circulating blood when the use of fuels for energy are at their peak during muscular work, so the I:G ratio is rather low. Glucagon is also of major importance during fasting. The levels of glucose and amino acids in the blood supplying the pancreas cause a response from the secretory cells to regulate these counter balancing secretions; i.e., a rise in blood glucose affects cell membrane receptors on beta cells, resulting in an increase in the synthesis and extrusion of insulin. The islet cells secrete additional hormones, such as gastrin and pancreatic polypeptide. Their interactions with glucagon and insulin are current research topics.
