If a drug that was an inhibitor of pp1 activity was ingested by a person

glycogen phosphorylase would be de-phosphorylated and inactive.
glycogen phosphorylase would be de-phosphorylated and retain some activity.
glycogen phosphorylase would remain phosphorylated and inactive.
glycogen phosphorylase would remain phosphorylated and retain some activity.

The correct answer is: Glycogen phosphorylase would remain phosphorylated and retain some activity.

Glycogen phosphorylase is directly involved in the regulation of glucose levels since it is a glucose sensor in liver cells: when glucose levels are low, phosphorylase is active and it has PP1 bound to it (phosphatase activity of PP1 is prevented). Therefore, there phosphorylase a will accelerate glycogen breakdown.
