Epinephrine, the fight-or-flight hormone, acts via cyclic adenosine monophosphate (cAMP). cAMP is a second messenger produced when adenosine triphosphate (ATP) undergoes an enzyme catalyzed reaction.a) Select the appropriate enzymes responsible for the production of cAMP and adenosine monophosphate (AMP).ATP --------(?)----------> cAMP ---------------(?)--------------> AMPOptions: adenylate cyclase, phosphodiesterase, ATPaseb) Draw the structure of cAMP
