Quizplus · Accepted Answer

The cyclic AMP signaling pathway relies on the production of cAMP through the activation of adenylate cyclase (AC) by GTP-binding proteins (G proteins) that are coupled to receptors, such as the G protein-coupled receptor (GPCR) rhodopsin. Hydrolysis of GTP is necessary to turn off the signaling pathway and subsequent synthesis of cAMP.

Note: Option I (cyclic AMP) is not the best answer as it is the product of the signaling pathway, not the pathway itself.
