Glycogenolysis Glycolysis Krebs cycle Gluconeogenesis. Control of carbohydrate metabolism. Low energy state prevents anabolism, favors catabolism High energy state favors and is required for anabolism.
Hormones regulate carbohydrate metabolism through. Gene expression Second messenger system. Major hormones that regulate CHO metabolism.
Insulin Glucagon Glucocorticoid hormones. Glucose enters the cells of most tissues. Glucose entry into myocytes and adipocytes. Glucose entry into the liver is not regulated by insulin via the membrane receptor,. After entry into the liver, glucose is.
Glucose 6-phosphatase converts GP to. Glucose is converted into glycogen for storage in liver, muscle and to a small extent in adipose. Hexokinase in most body cells. High affinity for glucose Low specificity for monosaccharides Allosteric; inhibited by product GP.
Specific for glucose, but low affinity Not inhibited by product GP Induced by insulin; circulating [insulin] increases in response to high blood glucose such as after a meal AKA hexokinase D. Isomerization phosphoglucomutase Glucose 6-P to Glucose 1-P. Glucose is incorporated into glycogen as UDP-glucose. Glucose 6-phosphate is a. Glucose residues are cleaved one at a time from glycogen to be.
Reactions 1 and 2 occur in. Only the liver contains. Through the addition of phosphate, glycogen phosphorylase cleaves 1 glucose residue from glycogen, forming glucose 1-phosphate. Glycogen phosphorylase is regulated by.
