Detailed explanation-1: -Another important group of second messengers are the cyclic nucleotides, specifically cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) (Figure 8.7C). Cyclic AMP is a derivative of the common cellular energy storage molecule, ATP.
Detailed explanation-2: -Option B: cAMP: Cyclic AMP is formed from ATP by the action of enzyme. Changing the molecular activities in the cytosol, uses PKC (protein kinase A). It is a second messenger.
Detailed explanation-3: -Cyclic adenosine monophosphate (cAMP) is a second messenger used for intracellular signal induction. It is synthesized from adenosine triphosphate (ATP) by enzymes (g-proteins) that are attached to metabotropic receptors and become released when the receptor is activated.
Detailed explanation-4: -(A) cAMP is the archetypical second messenger. Its levels increase rapidly following receptor-mediated activation of adenylyl cyclase (AC), which catalyzes the conversion of adenosine monophosphate (AMP) to cAMP.
