Quizplus · Accepted Answer

During the breakdown of glycogen by glycogen phosphorylase, the enzyme removes glucose monomers from the nonreducing end of the glycogen chain and converts them into glucose-1-phosphate. This is the immediate predominant product of glycogenolysis. UDP-glucose is an intermediate in the synthesis of glycogen, and glucose-6-phosphate is formed in the conversion of glucose-1-phosphate to glucose-6-phosphate by the enzyme phosphoglucomutase. However, glucose-1-phosphate is the immediate product of glycogen phosphorylase. Therefore, option B is correct.
