To determine: The event that occurs when the liver cell is exposed to epinephrine and a drug that inhibits protein kinase A at the same time.

Introduction: Cell signaling is the process of cell communication within the body. Epinephrine, which is commonly called as adrenaline, is secreted by the adrenal glands and a small amount in the neurons of the medulla oblongata. It plays an important role in the glucose metabolism by binding to its receptor molecules of cells.
