If a person is being treated for shock and receives an injection of epinephrine to aid recovery, you would expect to see all of the following except
A) decreased production of cAMP in liver cells.
B) increased activation of glycogen phosphorylase.
C) decreased amounts of glycogen in liver cells.
D) increased activity at epinephrine receptors.
E) increased activation of adenylyl cyclase.

Question

Quizplus · Accepted Answer

Epinephrine stimulates the activation of adenylyl cyclase, which leads to an increase in cAMP levels in liver cells. Increased cAMP levels activate glycogen phosphorylase, which leads to the breakdown of glycogen into glucose. Therefore, choices B, C, D, and E are all expected effects of epinephrine administration in the treatment of shock. Choice A, on the other hand, is incorrect, as epinephrine causes an increase, not a decrease, in the production of cAMP in liver cells.
