What is the role of the enzyme phosphoglucomutase in glycogenolysis?

A To convert glucose-1-phosphate to glucose-6-phosphate
B To convert glycogen to glucose-1-phosphate
C To convert glucose-6-phosphate to glucose-1-phosphate
D To convert fructose-6-phosphate to fructose-1,6-bisphosphate
Phosphoglucomutase is an enzyme that catalyzes the conversion of glucose-6-phosphate to glucose-1-phosphate, a key step in glycogenolysis.
