In the nitric oxide signaling pathway, nitric oxide activates an enzyme that can convert many molecules of GTP into molecules of cGMP. cGMP is a small molecule that can diffuse through the cytoplasm and bind to an enzyme called protein kinase G (PKG).

A. adapter protein B. enzyme C. second messenger D. scaffold
