Glycogenolysis does not occur in muscle tissue because it lacks which of the following enzymes?

Question

This means that glucose-6-phosphate generated during glycogenolysis in muscles cannot be converted back into glucose and exported from muscle cells, limiting the ability of muscles to raise blood glucose levels during prolonged exercise or fasting.
