<prompt> Decreased glucose concentration in hepatic cells triggers all of the following exceptIncreased glucagon levels in bloodActivation of fructose-2,6-biphosphataseInhibition of phosphofructokinase-2Increased fructose-2,6-biphosphate levels  <response>: Decreased glucose level leads to increased levels of glucagon .Glucagon inhibits activity of PFK-2, and stimulates the activity of Fructose 2,6 biphosphatase .Activation of fructose-2,6-biphosphatase leads to decreased level of fructose-2,6-biphosphate levels .Ref: Harpers illustrated Biochemistry 27th ed.
