Quizplus · Accepted Answer

The phosphoinositide signaling pathway plays a role in regulating cytosolic calcium ion levels through the production of inositol triphosphate (IP3), which causes the release of calcium ions from the endoplasmic reticulum.

Answer: D
 Calmodulin is a calcium-binding protein that regulates many calcium-dependent processes inside cells, including the activity of calcium channels, pumps, and exchangers that control cytosolic calcium ion levels.
