A typical adult human body contains about ______ of magnesium.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 25 g.
- An adult body contains approximately 25 g magnesium.
- Magnesium is a component of bone; in fact 60% of the body's magnesium is stored in bone.
- Less than 1% of total magnesium is in blood serum, and these levels are kept under tight control.
- It is also involved with the activity of bone-building cells and the parathyroid hormone, which regulates calcium levels.
