Question

1. Why is the sodium-potassium transport mechanism called a "pump"?

Answer 1

It's simply denotes to

• entrance of Sodium ion(Na+)
• Exit of potassium ion (K+)

This happens because of density tendency

They use the energy source as ATP or adrenosine tri phosphate

Answer 2

It pumps Na+ (Sodium) into the cell, and it pumps K+ (Potassium) out of the cell.

Step-by-step explanation:

It uses active transport, which is why it is a pump; pumps use energy in the form of ATP.
