If a portion of the pancreas is surgically removed from a rat and the rat subsequently loses its appetite, one explanation is that the removed portion contains cells that secrete a chemical signal that somehow stimulates appetite. Given this scenario, what type of chemical signaling is occurring?

Choose the correct statement of the following

a. In general, high acetyl-CoA or citrate are present, or when a high proportion of the cell’s adenylate is in the form of ATP, gluconeogenesis is favored.

b. When the level of AMP increases, it promotes glycolysis by stimulating PFK-1 by inhibiting FBPase-1

c. Phosphorylation of fructose 6-phosphate, catalysed by phosphofructokinase-2 (PFK-2)

d. Glucagon increases the cellular level of fructose 2,6 bisphosphate, stimulating glycolysis and inhibiting gluconeogenesis.

Glucagon stimulates cAMP from ATP. Cyclic AMP then activates cAMP-dependent protein kinase, phosphorylates PFK-2/FBPase-2. Phosphorylation of this protein enhances its FBPase-2 activity and inhibits its PFK-2 activity resulting
