When the blood glucose concentration is low, the pancreas secretes glucagon to signal the liver to produce glucose and glucose-1-phosphate. Which metabolic steps are involved in this biosignaling pathway

See below (Correct I and IV)

Explanation:

Inactivation of glycogen synthase via phosphorylation by protein kinase A

Activation of glycogen synthase via phosphorylation by protein kinase A

Activation of phosphofructokinase-2 via phosphorylation by protein kinase A

Activation of fructose-2,6-bisphosphatase via phosphorylation by protein kinase A

Activation of phosphofructokinase-1 by fructose-2,6-bisphosphate

Inhibition of fructose-1,6-bisphosphatase by fructose-2,6-bisphosphate

Inactivation of pyruvate kinase via phosphorylation by protein kinase A

Glycogenolysis: It is the process by which glycogen stored in liver and muscle cells, break down to form glucose.
