Which is the predominant second messenger involved in regulating glucose metabolism?
A) ATP
B) ADP
C) mRNA
D) cAMP
E) NADH

Question

Quizplus · Accepted Answer

cAMP is the predominant second messenger involved in regulating glucose metabolism. It activates protein kinase A (PKA), which in turn phosphorylates key enzymes and transcription factors involved in glucose metabolism. ATP and ADP are also involved in regulating glucose metabolism but do not act as second messengers. mRNA and NADH are not second messengers and do not directly regulate glucose metabolism.
