Textbook Question
Chapter 11, Problem 11TYK
From studying the effects of epinephrine on liver cells, Sutherland concluded that
- a. there is a 1-to-10,000 correlation between the number of epinephrine molecules bound to receptors and the number of glucose molecules released from glycogen.
- b. epinephrine enters liver cells and binds to receptors that function as transcription factors to turn on the gene for glycogen phosphorylase.
- c. there is a “second messenger” that transmits the signal of epinephrine binding on the plasma membrane to the enzymes involved in glycogen breakdown inside the cell.
- d. epinephrine functions as a ligand to open ion channels in the plasma membrane that allow Ca2+ to enter and initiate a response.
