Discuss whether glucagon and epinephrine act in the same way in liver, muscle and heart cells in terms of their effects on glycolysis and gluconeogenesis

Solutions

Expert Solution

Glucagon responds when glucose is too low, and the tissues respond by producing glucose through glycogen breakdown and gluconeogenesis and by oxidizing fats to reduce the use of glucose.Epinephrine is released into the blood to prepare the muscles, lungs, and heart for a burst of activity.Glucagon has potent positive inotropic and chronotropic effects on the heart. This endogenous hormone plays no significant role in the normal regulation of the cardiovascular system, but it has been used to treat various cardiac conditions. Glucagon and epinephrine trigger the breakdown of glycogen. Muscular activity or its anticipation leads to the release of epinephrine ,a catecholamine from the adrenal medulla. Epinephrine stimulates glycogen breakdown in muscle and in the liver. The liver is responsive to glucagon, a polypeptide hormone that is secreted by the α cells of the pancreas when the blood-sugar level is low. Glucagon also signifies the starved state.

Epinephrine and glucagon bind to different receptors on cell surface, but both receptors activate the same G protein and trigger the same series of events in which cAMP is produced and activates downstream proteins to regulate the metabolism of different types of carbohydrates. In lecture, we have learnt that activation of G protein by these two hormones promotes the breakdown of glycogen through the activation of glycogen phosphorylase and inhibition of glycogen synthetase in liver and muscle. In this essay,...

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.)

Upon being secreted from the pancreas, glucagon binds to the receptors on liver cells, which initiates a signaling cascade that regulates glycogen metabolism, glycolysis/gluconeogenesis, and fatty acid metabolism. Explain the following: 1. The metabolic conditions in which glucagon is released from the pancreas 2. How it affects metabolism of glycogen, glucose (glycolysis/gluconeogenesis), and fatty acids 3. Why it makes metabolic sense for glucagon to regulate these pathways in this manner in the liver cells.
