C there your answer i hope it help
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.

Step 1: 405kpa times 4cm^3 so 405/4=1620
Step 2: 1620 divide 6 so 1620/6=270
The final answer is 270Kpa
