Question

During Na${}^{+}$-K${}^{+}$pump,

• A. 3 Na${}^{+}$ and 2 K${}^{+}$ are transported.
• B. 1 Na${}^{+}$ and 2 K${}^{+}$ are transported.
• C. 3 Na${}^{+}$ and 3 K${}^{+}$ are transported.
• D. Depends on requirement of cell.

Answer 1

Answer: (A)

3 Na${}^{+}$ and 2 K${}^{+}$ are transported.

The Na and K ions pumping is an active transport process that involves the movement of sodium and potassium ions across the cell membrane by the use of required energy. This process that helps to maintain the amount of Na⁺ and K⁺ ions outside and inside of the cell. During this process, three Na⁺ is transported outside of the cell and two K⁺ ions are transported inside the cell.
