Explanation:
Detailed explanation-1: -The second messenger is the mechanism of the action of hydrophilic hormones with receptors in the target cells. The receptors for hydrophilic hormones are present on the plasma membrane of the target cells. The first messengers interact with receptors on cell membranes which form the Hormone-Receptor Complex.
Detailed explanation-2: -cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response.
