Glucose Metabolism General info on glucose metabolism. This game does not go over details on the steps of glycolysis-- it is more general. Tools A B Transports glucose across plasma membrane GLUT-1 Site of glucose metabolism red blood cells Major product of glycolysis ATP The storage form of glucose Glycogen Like insulin, regulates blood glucose Glucagon Keeps glutathione in reduced form NADPH Helps brain take up glucose GLUT-3 Transports glucose into muscle cells GLUT-4 Transports glucose into liver GLUT-2 Glycogen synthesis Glycogenesis Glycogen degradation Glycogenolysis Anaerobic degradation of glucose to lactate Fermentation When the presence of oxygen suppresses glycolysis Pasteur effect
