III.3.H. Regulation of the blood glucose level
Glu uptake and release are strongly regulated in the body. Physiologically, a high blood Glu level induces insulin release from the pancreatic B cells, and insulin induces Glu uptake in the tissues. A low blood Glu level induces glucagon synthesis in the pancreatic A cells, and glucagon enhances the release of Glu from the liver, thereby increasing the blood Glu level. In the cycle, the consumed or stored Glu is replaced from the food or from the breakdown mechanisms (Fig. 11).
