21. Glycerol and sorbitol are reconverted into glycogen at the termination of diapause. 22. After all this is done, glycogen phosphorylase can continue. 23. Glycogen phosphorylase kinase activates glycogen phosphorylase in the same manner mentioned previously.24. Glycogen phosphorylase kinase activates glycogen phosphorylase in the same manner mentioned previously. 25. Glycogenin remains covalently attached to the reducing end of the glycogen molecule. 26. Glycogen synthase can be classified in two general protein families.27. Glycogen -storage disease type 0 affects only the liver.28. The catabolic process occurs at the nonreducing end of glycogen . 29. Mutations in this gene have be associated glycogen storage disease. 30. After aerobic exercise, glycogen levels are lower than normal.
