Assertion : The imbalance in the concentration of $\mathrm{Na}^{+}, \mathrm{K}^{+}$and proteins generates the resting potential. Reason : To maintain the unequal distribution of $\mathrm{Na}^{+}$and $\mathrm{K}^{+}$, the neurons use electrical energy.
  1. If both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. If both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. If the assertion is true but the reason is false.
  4. If both assertion and reason are false.

Solution

To maintain the unequal distribution of $\mathrm{Na}^{+}$ and $\mathrm{K}^{+}$ion, the neuron uses chemical energy in the form of ATP to actively transport $\mathrm{Na}^{+}$ion out of the cell and move $\mathrm{K}^{+}$inside the cell.
