Quizplus · Accepted Answer

The molecule shown is ATP, which can be converted to cAMP through the action of the enzyme adenylate cyclase. Therefore, the correct answer is B. ADP is not a second messenger molecule, NAD⁺ is not a known molecule, and PKA is a protein kinase enzyme that can be activated by cAMP, but is not a second messenger molecule itself.
