In the signal cascade triggered by epinephrine within liver cells, glycogen synthase is
A) inactivated and does not produce glycogen.
B) activated and binds to glucose.
C) inactivated and produces glycogen.
D) activated by protein kinase A.
E) activated by cyclic AMP.

Question

Quizplus · Accepted Answer

Glycogen synthase is inactivated in the signal cascade triggered by epinephrine within liver cells, leading to a decrease in glycogen production. This is because epinephrine signals the breakdown of glycogen into glucose to provide energy quickly, not its synthesis.
