Q25 / 180 · NEET 2013 (All India) · Botany

The most abundant intracellular cation is

  • A
    $\mathrm{Na}^{+}$
  • B
    $\mathrm{Ca}^{2+}$
  • C
    $\mathrm{H}^{+}$
  • Correct answer
    D
    $\mathrm{K}^{+}$

Solution

Major intracellular cation is $\mathrm{K}^{+}$. Major extracellular cation is $\mathrm{Na}^{+}$. $\mathrm{Ca}^{+}$play major role in signal transduction pathways. $\mathrm{H}^{+}$is found in aqueous solution of all acids.
