Question 1: The key regulatory enzyme of the process of glycogenolysis is ________:
Glycogen synthaseGlycogen debranching enzymeGlycogen branching enzymeGlycogen phosphorylase

Question 2: ________ cells in humans do not possess glucose-6-phosphatase and hence will not release glucose, but instead use the glucose-6-phosphate in glycolysis.
