Question

Which one of the following ion pair is involved in nerve impulse transmission?

• A. $N{a}^{+},K^{+}$
• B. $N{a}^{+},C{l}^{-}$
• C. $K^{+},C{l}^{-}$
• D. $K^{-},C{a}^{2+}$

Answer 1

The correct option is A $N{a}^{+},K^{+}$

A nerve impulse is the means by which nerve cells (neurons) communicate with one another. Nerve impulses are generated by generation of action potential. The action potential is the result of ions moving in and out of the cell, specifically sodium (Na+) and potassium (K+) ions.

So, the correct option is A.
