Calcium ions could be described as "third messengers" because calcium ions could be described as "third messengers" because they function in three separate cellular compartments: cytosol, er, and mitochondria they are stored in compartments inside the cytoplasm, placing them in a third compartment after the extracellular and cytosolic spaces they are the third type of regulators released by a g protein-mediated signal cascade (camp = 1st ip3/dag 2nd) they are small cytosolic signal molecules whose activity is regulated first by a ligand and second by a second messenger, making them the third step in a cascade

Explanation:

Third messengers are cytosolic proteins which are associated with vesicles containing internalized receptors and which pass into the nucleus. They subsequently serves as transcription factors in the modulation of gene expression. Calcium ions is transported across the plasma membrane which allows them to be recycled as ‘third messengers’ extending their ability to convey information in a domain outside the cell. They are found to selectively activate a subset of targets, thereby expanding the repertoire and range of the signal. The intracellular cAMP signaling events are associated with extracellular accumulation of the second messenger, so that calcium ions can fluctuate outside cells, owing to activation of influx and efflux pathways for the cation Calcium ions signaling events. The steps involved include ;
