Which of the following statements regarding glycogen metabolism is FALSE?

Which of the following statements regarding glycogen metabolism is FALSE?








The rate-limiting reaction in glycogenolysis is a phosphorolysis reaction which generates glucose-1- phosphate.








Starting from glycogen stores, the net yield of ATP per molecule of glucose proceeding through glycolysis is greater in skeletal muscle than in the liver.








In skeletal muscle, glycogen phosphorylase is not regulated by glucagon.








Skeletal muscle cannot export glucose because it does not contain the enzyme glucose-6-phosphatase.
