Question

Soidum potassium pumps in the axonal membrane ionic gradients across the resting membrane by

• A. Passive transport of $N{a}^{+}$ outwards and $K^{+}$ inwards
• B. Active transport of $N{a}^{+}$ inwards amd $K^{+}$ outwards
• C. Transport of $N{a}^{+}$ and $K^{+}$ ions along their concentration gradients.
• D. Active transport of $N{a}^{+}$ outwards and $K^{+}$ inwards

Answer 1

The correct option is D Active transport of $N{a}^{+}$ outwards and $K^{+}$ inwards

Sodium-potassium pumps in the axonal membrane ionic gradients across the membrane by active transport of Na$+$ outwards and K$+$ inwards.

So, the correct option is 'Active transport of Na+ outwards and K+ inwards'.
