Question

Assertion: The imbalance in concentration of $N{a}^{+}$, $K^{+}$ and proteins generates resting potential.
Reason: To maintain the unequal distribution of $N{a}^{+}$ & $k^{+}$, the neurons use electrical energy.

• A. If both the assertion and the reason are true and the reason is the correct explanation of the assertion
• B. If both the assertion and the reason are true and the reason is not the correct explanation of the assertion
• C. If the assertion is true and the reason is false
• D. If both the assertion and the reason is false
• E. If the assertion is false but the reason is true

Answer 1

The correct option is C If the assertion is true and the reason is false

To maintain the unequal distribution of $N{a}^{+}$ and $?K^{+}$ ions, the nerves uses chemical energy in form of ATP to actively transport $N{a}^{+}$ ion out of cell and more $K^{+}$ inside the cell.
