Question

${Na+K}^{+}$ pump represents

• A. Active transport
• B. Passive transport
• C. Osmosis
• D. Simple diffusion

Answer 1

Answer: (A)

Active transport

The sodium-potassium pump is a specialized mechanism to transport proteins using energy. The process of moving sodium and potassium ions across the cell membrane is an active transport as it involves the hydrolysis of ATP. The hydrolysis of ATP molecule provides the necessary energy for the transport of molecules across the membrane. The action involves an enzyme known as Na+/K+-ATPase.

So, the correct answer is 'Active transport'.
