Regulation of glycogen metabolism does not include _____

Glycogen molecules are stored in liver and --------------

The body's largest stores of glycogen are found in the liver and skeletal muscles.  Individual glucosyl residues (ie, glucose monomers) in muscle and liver glycogen particles are linked by α(1→4) and α(1→6) glycosidic bonds and are released in the reactions of glycogenolysis.  Glycogen phosphorylase catalyzes the removal of most of the glucosyl residues, although debranching enzyme also releases the single glucose molecule that remains after it repositions three residues onto an adjacent linear chain.Binding of the hormone epinephrine to its receptor on the surface of muscle cells stimulates muscle glycogenolysis through activation of a signaling cascade (Figure 1).Figure 1  Stimulation of skeletal muscle glycogenolysis by epinephrine.The relative signal amplification (SA) at each step (I–IV in Figure 1) can be determined by comparing the number of active signaling molecules before (Mbefore) and after (Mafter) the step:SA=MafterMbeforeSA=𝑀after𝑀before Question 36The skeletal muscles collectively contain more than twice as much glucose stored in glycogen as is found in the liver.  Compared with the liver, the amount of glucose released into the blood from muscles is likely:A.greater from glycogenolysis, but less from gluconeogenesis.B.the same from glycogenolysis, but more from gluconeogenesis.C.less from both glycogenolysis and gluconeogenesis.D.the same from both glycogenolysis and gluconeogenesis.
