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

Correct (b) I and IV

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

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
