Glycogen storage disease type I as fat. When digestion of a meal is complete, insulin levels fall, and enzyme systems in the liver cells begin to remove glucose molecules from strands of glycogen in the form of G6P. This process is termed glycogenolysis. The G6P remains within the liver cell unless the phosphate is cleaved by glucose-6-phosphatase. This dephosphorylation reaction produces free glucose and free anions. The free glucose molecules can be transported out of the liver cells into the blood to maintain an adequate supply of glucose to the brain and other organs of the body. Glycogenolysis can supply the glucose needs of an
Stress in early childhood the skin and gut. This allows a sufficient amount of blood to access the brain and muscles. Also, epinephrine initiates the breakdown of glycogen in the liver, in turn increasing blood glucose levels. This energy source allows humans to enact defensive responses due to stress. In the human body, the steps that lead to the release of glucocorticoids such as cortisol begin with the release of corticotropin releasing hormone (CRH) and arginine vasopressin (AVP). These hormones travel through the blood vessels to the anterior pituitary gland of the brain. At this location, adrenocorticotropic hormone (ACTH) is released. ACTH binds to
