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
Absorptive state Absorptive state Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism. The fuel used for this process is glucose. Carbohydrates - Simple sugars are sent to the liver where they are converted to glucose. The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state. The remaining glucose is taken in for use by body cells or stored in skeletal muscle as glycogen. Triglycerides - Chylomicrons, the
