Q. 12. Explain Na - K exchange pump.
Ans. Sodium-potassium exchange pump:
(a) It is a multi-purpose active transport carrier protein.
It turns Na+ out and K+ in with energy of ATP. Na+ gradient; then powers active transport of sugars as well as the amino acids into cell.
(b) Sodium pump regulates cell's water content indirectly by actively transporting Na+ and K+ ions through cell membrane.
(c) The water then moves passively through the process of osmosis to an area having lower osmotic pressure.
