What is glycogenolysis? Correct Answer-Phosphorolysis (NOT hyrdolysis) of the glycosyl residues at the NONREDUCING end of glycogen. This means the Pi (NOT HOH) is used to release a glucose residue at the NONREDUCING end of glycogen. What enzyme is necessary for glycogenolysis? Correct Answer-Glycogen phosphorylase When a glucose-1-P molecule is released from glycogen, it can be metabolized by 2 different pathways depending on the tissue. What are the 2 pathways? Correct Answer-1) Muscle, b...
