Assertion : The imbalance in the concentration of Na^ + , K^ + and...

Assertion : The imbalance in the concentration of Na+,K+\mathrm{Na}^{+}, \mathrm{K}^{+}and proteins generates the resting potential. Reason : To maintain the unequal distribution of Na+\mathrm{Na}^{+}and K+\mathrm{K}^{+}, the neurons use electrical energy.

Options

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. DIf both assertion and reason are false.

Correct answer

C. If the assertion is true but the reason is false.

Step-by-step solution

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