cGMP is a second messenger in the nitric oxide signaling pathway. What enzyme is responsible for production of cGMP?
A) adenylyl cyclase

C) phosphodiesterase
D) protein kinase G

Question

Quizplus · Accepted Answer

Guanylyl cyclase is responsible for the production of cGMP in the nitric oxide signaling pathway. Adenylyl cyclase produces cAMP, another important second messenger. Phosphodiesterase breaks down cAMP and cGMP. Protein kinase G is a downstream target of cGMP and is responsible for many of its cellular effects.
