The step in which the signal gets amplified and the way in which amplification takes place have to be described briefly. Concept Introduction: Hormones: Hormones are chemical messengers which are secreted by the cell in endocrine system and are transported along the blood to stimulate the target cells having the corresponding receptors. There are three proteins which are involved in the releasing of a hormone signal. They are receptor, G protein and an enzyme. 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”. 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.
