Which of the following would likely not be observed in a person injected with epinephrine?
A) Decreased production of cAMP in liver cells
B) Inactivation of glycogen synthase
C) Increased glucose mobilization
D) Activation of G proteins
E) All of the above would be observed.

Question

Quizplus · Accepted Answer

Epinephrine acts on liver cells by binding to beta-adrenergic receptors, which activates G proteins and stimulates the production of cAMP. This leads to the activation of glycogen phosphorylase and the breakdown of glycogen into glucose. Therefore, A would not be observed, as epinephrine would increase the production of cAMP in liver cells. The other options, B through D, would be observed in a person injected with epinephrine.
