Question

Decreasing order concentration of minerals inside cell is

• A. Ca${}^{+2}$$-$K${}^{+}$$-$Na${}^{+}$.
• B. K${}^{+}$$-$Ca${}^{+2}$$-$Na${}^{+}$.
• C. K${}^{+}$$-$Na${}^{+}$$-$Ca${}^{+2}$.
• D. Na${}^{+}$$-$K${}^{+}$$-$Ca${}^{+2}$.

Answer 1

The correct option is C

K${}^{+}$$-$Na${}^{+}$$-$Ca${}^{+2}$.

Potassium ions are usually higher inside the cell than outside the cell, and its concentration inside the cell is about 10 to 30 fold higher than the other components, while sodium ion is higher outside the cell than inside the cell.

So, the answer is C.
