<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 the 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.
