Final answer:
The correct sequence of actions of a nonsteroid hormone using cyclic AMP is Reception, Signal Cascade, Second Messenger.
Step-by-step explanation:
The correct sequence of actions of a nonsteroid hormone using cyclic AMP is b) Reception, Signal Cascade, Second Messenger.
In this pathway, a water-soluble hormone first binds to its receptor in the cell membrane, which activates a G protein associated with the receptor. The activated G protein then activates an enzyme called adenylyl cyclase, which converts ATP into cyclic AMP (cAMP) as the second messenger. The cAMP then activates protein kinases, initiating a phosphorylation cascade that affects various cellular proteins and enzymes.
