The participation of nitric oxide in signal transduction
A) depends upon interaction with a heterotrimeric guanine nucleotide-binding protein.
B) is mediated by a receptor localized in the nucleus.
C) requires the oxidation of lysine by nitric oxide synthase.
D) results in the activation of guanylyl cyclase.

Question

Quizplus · Accepted Answer

Nitric oxide binds to guanylyl cyclase, which then catalyzes the conversion of GTP to cGMP, resulting in downstream signaling events. This is the mechanism by which nitric oxide participates in signal transduction.
