What is the function of glycogen phosphorylase in muscle cells? A. Covalent attachment of glucose to glucogenin by transglucosylation B. Breakdown of glycogen to supply glucose to the bloodstream C. Synthesis of glycogen from UDP-glucose for energy storage D. Breakdown of glycogen to glucose 1-phosphate for glycolysis E. Synthesis of branched glycogen by 1->4 to 1->6 transglycosylation 2. What is the expected consequence of McArdle's disease, which is caused by a glycogen phosphorylase deficiency in myocytes (muscle cells)? A. Hypoglycemia (low blood sugar) due to lower myocyte glucose transport B. Low levels of glycogen storage due to inactivation of glycogen synthase C. Hyperglycemia (high blood sugar) due to low flux of glycolytic metabolites D. Insufficient supply of glucose to support glycolysis during exertion E. Increased gluconeogenesis activity in myocytes to replenish glucose 3. In muscle cells, which is not a potential fate of glucose 6-phosphate? A. Glycolysis B. Glycogen synthesis C. Pentose phosphate pathway D. Export by GLUT-2 E. Glycosylation of proteins

1. Glucagon causes a set of reactions that leads to stimulation of glycogenolysis. The higher cAMP levels caused a drop in fructose-2,6-bisphosphate levels. Determine what would happen to glucose-6-phosphate generated from glycogenolysis - do you think they would be exported to blood or processed via glycolysis? a. none are correct b. glycogenesis increased in liver c. glycogenesis decreases in muscle d. glycolysis inhibited in liver b/c fructose-2,6-bisphosphate would deactivate phosphofructokinase e. in muscle glucose-6-phosphate is released into blood directly as glucose-6-phosphate b/c it doesn't have enzyme 'glucose-6-phosphatase' f. Glucose-6-phosphate is dephosphorylated to glucose and exported to blood via hepatocytes (liver cells)
