Caffeine prolongs and intensifies the effects of epinephrine. Which of the following potential mechanisms of action of caffeine
kherson [118]

Answer:

a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.

Explanation:

The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.
