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

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 ;

The release of calcium ions from internal storage compartments into the cytoplasm via intracellular release channelsThe extrusion of calcium ions into the extracellular space by plasma membrane calcium ions ATPases or other export mechanisms.The activation of calcium ions through spore-operated channels.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.

Athief was passing by a house under construction when he noticed that the ladder being used by workers on the roof had copper braces supporting the rungs. after making sure that the workers on the roof could not see him, the thief used pliers that he had in his pocket to remove all of the copper braces that he could reach from the ground. a short time later, a worker climbed down the ladder and it collapsed. he fell to the ground and severely injured his back. the thief was apprehended a few hours later trying to sell the copper for scrap. a statute in the jurisdiction makes it a felony for "maliciously causing serious physical injury to another." the thief was charged with malicious injury under the statute and was also charged with larceny. after a jury trial in which the above facts were presented, he was convicted of both charges. if he appeals the conviction for the malicious injury charge on grounds of insufficient evidence, how should the court rule? a affirm the conviction, because the thief was engaged in criminal conduct at the time of the act that resulted in the injury. b affirm the conviction, because the jury could have found that the thief acted with malice. c reverse the conviction, because there was no evidence that the thief intended to injure anyone. d reverse the conviction, because there was no evidence that the thief bore any malice towards the workers on the roof.
