Question: 1 / 400

What is the extracellular concentration of magnesium in mmol/L?

1

The extracellular concentration of magnesium is typically around 1.0 mmol/L. This level is essential for various physiological functions, including muscle contraction, nerve function, and cellular processes. The body maintains this concentration within a narrow range to ensure proper biological functioning. While options such as 2 or 10^-4 have values that do not accurately reflect the typical physiological range for extracellular magnesium, the choice of 26 mmol/L is also significantly higher than what is observed in normal conditions. Thus, the value of 1 mmol/L aligns with established physiological references, confirming it as the correct choice for the extracellular concentration of magnesium.
