Answer 1

In the mechanism of action of a protein hormone, one of the second messengers is cyclic AMP.

Explanation:

Hormones which interact with membrane-bound receptors normally do not enter the target cell, but generate secondary messengers (e.g., cyclic AMP, cGMP, DAG, IP₃, Ca⁺⁺ etc.) which in turn regulate cellular metabolism.
