Possible activation of several different second messenger systems.
"Messenger".
inositol triphosphateInositol triphosphate (IP3) and diacylglycerol (DAG) are important second messengers. Their formation begins with the binding of an extracellular regulatory
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.
The first messenger is nothing but referred to the molecule that brings information upto the cell surface. Once this molecule transfers signal to cell, it is taken over by the well known second messenger to take it further to nucleus through various other signaling molecules down the cascade.

The largest order of mammals, with about 1,700 species, is rodents. Bats are second with about 950 species.
Protein kinase A is activated by the second messenger through a process called phosphorylation. When the second messenger binds to the regulatory subunit of protein kinase A, it causes a conformational change that releases the catalytic subunit. This released catalytic subunit is then able to phosphorylate target proteins, leading to various cellular responses.
A neurotransmitter whose function depends on a second messenger is known as a neuromodulator. Neuromodulators can influence the behavior of neurons by affecting processes like signal transduction or synaptic transmission.
Peptide hormones bind to cell surface receptors, activating signaling pathways that involve the generation of second messengers within the cell. The first messenger (peptide hormone) triggers the activation of specific proteins or enzymes that then generate the second messenger molecules, such as cyclic adenosine monophosphate (cAMP) or inositol trisphosphate (IP3), initiating a cascade of cellular responses.
