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
Adenosine monophosphate deaminase deficiency type 1 itself), that requires prolonged vigorous chewing, and then some time to be digested, for instance parboiled long grain rice, chewing may suddenly become very slow and difficult halfway through the meal. When a carbohydrate-rich food has been eaten before AMP has been eliminated from muscle cells, when bulk absorption starts, plenty of glucose becomes available in the blood, is taken up by muscle cells, is added to the glycogen store, but then immediately becomes liberated by the still up-regulated myophosphorylase. The resulting excess of glucose is metabolized down to lactic acid (the body cannot increase aerobic metabolism in an instant),
