Explanation:
The permissive effect is the one in which the presence of one hormone enables another hormone to act
Epinephrine is an endocrine hormone produced by adrenal glands in stress condition and prepare body for fight and flight
Thyroid hormones exert their effects by binding to a specific nuclear receptors to regulate cellular gene expression
Receptor associated with epinephrine signaling are [tex]\alpha[/tex]1,[tex]\alpha[/tex]2,β1 and β2
β1 associated trimeric G protein is GS which activate adenylate cyclase enzyme which catalyse production of a potent secondary messenger called cAMP
