Heart muscle contains a form of PFK-2/FBPase-2 that is different from that in liver. In heart muscle, phosphorylation of PFK-2/FBPase-2 by protein kinase A (also called cAMP-dependent protein kinase) activates PFK-2 and inhibits FBPase-2. Explain why this makes metabolic sense for a response of heart muscle to epinephrine. (Heart muscle cells have receptors for epinephrine, but not for glucagon.)

A mutation in the liver enzyme PFK-2/FBPase-2 results in the loss of cAMP-dependent kinase phosphorylation site, thus resulting in a loss of responsiveness to cAMP-dependent kinase. What are the effects of this mutation on blood glucose levels during times of fasting? Please explain your answer.

Muscle and liver have different roles in the regulation of carbohydrate metabolism. For example, in the fight‑or‑flight response, muscle responds to epinephrine by modulating glucose pathways to achieve rapid ATPATP production. In contrast, in conditions where blood glucose levels fall, liver responds to glucagon by producing glucose for export into the bloodstream. Using the metabolic map as a resource, locate the glucose pathways on the map.
