The role does the second messenger play in a cell stimulated by epinephrine should be determined. Concept introduction: Epinephrine (or adrenaline) is a hormone secreted by the medulla of the adrenal glands. It is produced in times of stress such as excitement, danger, noise … Secondary messengers are short lived intracellular signaling molecules. Elevated concentration of these types of messengers leads to rapid alteration in the activity of one or more cellular enzymes. cAMP is a cyclic nucleotide and it is a second messenger which is synthesized from ATP by the action of the enzyme adenylyl cyclase. Chemically cAMP is a 3’,5’- adenosine monophosphate. Enzymes are proteins that increase the rate of reaction by lowering the energy of activation and so they are known as “biological catalysts” Phosphodiesterase is an enzyme that breaks a phosphodiester bond. This enzyme plays a key role in regulating intracellular levels of the second messenger cAMP and hence cell function.
