<span>The correct answer is calcifediol or calcidiol.</span>
<span>It is a prehormone that is produced in the liver. The mechanism of production includes hydroxylation of vitamin D3 (cholecalciferol) by the enzyme cholecalciferol 25-hydroxylase. Because it is the major form of vitamin D in the blood, it is considered the best indicator of vitamin D status. Calcidiol is converted in the kidneys into calcitriol which is the active form of vitamin D. </span>

Answer:

facts: The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

opinions: Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
