The first messenger for cyclic adenosine monophosphate (cAMP) is a hormone or ligand that binds to a G protein-coupled receptor, leading to activation of adenylate cyclase and conversion of ATP to cAMP. For cyclic guanosine monophosphate (cGMP), the first messenger is typically nitric oxide (NO) which activates guanylyl cyclase leading to the production of cGMP from GTP.

What is cyclic AMP produced by?
Cyclic AMP (cAMP) is produced by the enzyme adenylate cyclase, which converts ATP into cAMP in response to various signaling molecules such as hormones or neurotransmitters. The cAMP molecule then acts as a second messenger to relay extracellular signals into the cell to regulate various cellular processes.
What is Cyclic Amp cyclic GMP and PIP2 calcium?
Cyclic AMP is a form of adenylic acid responsible for regulating enzyme-catalyzed processes in living cells while PIP2 calcium is a membrane phospholipid.
What is cyclic AMP concentration?
Cyclic AMP, or cAMP, is a small molecule that plays a critical role in cellular signaling. It is synthesized from ATP by the enzyme adenylate cyclase and acts as a second messenger to regulate various cellular processes, including metabolism, gene expression, and cell growth. The concentration of cAMP in a cell can vary depending on external signals and internal regulatory mechanisms.
Does cyclic amp bind to calmodulin?
No, calcium bonds to calmodulin
What is cAMP and AMP?
cAMP (cyclic adenosine monophosphate) is a molecule that acts as a secondary messenger in cells, helping to regulate various cellular processes such as metabolism and gene expression. AMP (adenosine monophosphate) is a precursor molecule that can be converted into ATP (adenosine triphosphate), an energy carrier in cells.
Why is cyclic AMP a secondary messenger?
because original message is carried by hormone, which cant act directly, so in turn it activates cyclic AMP.
What is cyclic AMP produced by?
Cyclic AMP (cAMP) is produced by the enzyme adenylate cyclase, which converts ATP into cAMP in response to various signaling molecules such as hormones or neurotransmitters. The cAMP molecule then acts as a second messenger to relay extracellular signals into the cell to regulate various cellular processes.
What is the the role of cyclic AMP in cell proliferation?
Cyclic AMP is a secondary messenger that regulates cell proliferation by activating protein kinase A (PKA). PKA then phosphorylates target proteins involved in cell cycle progression, gene expression, and other cellular processes that drive cell proliferation. Overall, cyclic AMP signaling pathways play a crucial role in coordinating the cell's response to proliferative signals.
Which of the following does not act as a second messenger in the second messenger system calmodulin or inositol triphosphate or cyclic AMP?
inositol triphosphateInositol triphosphate (IP3) and diacylglycerol (DAG) are important second messengers. Their formation begins with the binding of an extracellular regulatory
What is Cyclic Amp cyclic GMP and PIP2 calcium?
Cyclic AMP is a form of adenylic acid responsible for regulating enzyme-catalyzed processes in living cells while PIP2 calcium is a membrane phospholipid.
What is the last step in the sequence of events when cyclic AMP acts as a second messenger?
the last step is ofcourse glycogen breakdown.......before that inactive glycogen phosphorylase-b is activated and phosphorylated to glycogen phosphorylase-a by the help of activated phosphorylase kinase........ ......phosphorylase kinase was activated by activated protien kinase..and activated protien kinase was activated by cyclic amp...........

The concentration of cAMP in a cell can vary depending on external signals and internal regulatory mechanisms.
Which substance is called the second chemical messenger?
Cyclic AMP (cAMP) is often referred to as the second messenger in signal transduction pathways. It is a key component in mediating intracellular responses to extracellular signals such as hormones and neurotransmitters.
Does cyclic amp bind to calmodulin?
No, calcium bonds to calmodulin
What is cAMP and AMP?

AMP (adenosine monophosphate) is a precursor molecule that can be converted into ATP (adenosine triphosphate), an energy carrier in cells.
How would a molecule that mimics cyclic AMP affect an olfactory receptor?
A molecule that mimics cyclic AMP can activate olfactory receptors by binding to their target site, triggering a cascade of intracellular signals similar to the natural activation of the receptor by cyclic AMP. This can lead to the perception of a smell even in the absence of the actual odorant molecule.
What role does cyclic AMP play for most hormones?
Cyclic AMP (cAMP) serves as a second messenger for many hormones. When hormones bind to their specific receptors on the cell membrane, it triggers a cascade of biochemical events that lead to the production of cAMP. cAMP then activates other signaling molecules, such as protein kinase A, which regulate various cellular processes, including gene expression, metabolism, and cell growth.
