Question

How does sodium and potassium pump work on nerve cells?

Answer 1

Hint: The sodium and potassium pumps are used as transporters for ions and molecules across the cell membrane. The sodium pump pumps out and potassium pumps ion in a fixed ratio across the cell membrane.

Complete answer:
$N{a^ + }/{K^ + }$ ATPase is also called $N{a^ + }/{K^ + }$ pump which helps in nursing anti porter like protein situated within the cell membrane of all animal cells. $N{a^ + }/{K^ + }$ ATPase protein pumps require oxygen out of the cell whereas pumping other elements into the cells. The method of moving oxygen and element ions across the cell wall is a lively transport process which involves the chemical reaction of nucleotides to supply the required energy. When the charge separation across the membrane is referred the nerve fibre membrane is maintained, the nerve cell is alleged to be at rest. This condition is completely referred to as electric potential.
A resting nerve cell is charged on the inner aspect and is charged on the fibre outer aspect such a charge separation is called polarization and therefore resting nerve cell is alleged to be polarized, this fibre potential, the nerve fibre membrane is relatively additional leaky to metal ions and nearly impermissible to oxygen ions.
The membrane is water repellent to charged proteins present at the intervals in the axoplasm and co-jointly $N{a^ + }$ , the axoplasm contains high concentrations of ${K^ + }$and negatively charged proteins and low concentration of $N{a^ + }$ .In distinction the humor contains high concentration of $N{a^ + }$and low concentration of ${K^ + }$. These ionic molecules move across the resting membrane area unit maintained by the transport of ions by the sodium –potassium pumps that transport $3N{a^ + }$outwards for $2{K^ + }$ into the cells on the worth of $1$ adenosine triphosphate. Therefore the outer surface of the nerve fibre membrane possesses an electric charge whereas its inner surface becomes charged.

Note: The sodium and potassium pump is crucial if it stops operating then $N{a^ + }$are going to be excess within the liquid body substance. The $N{a^ + }/{K^ + }$pump placed within the cytomembrane of the cells is like an associate degree antiporter like the protein found in animal cells. The fast movement of ions from humor to within the vegetative cell ends up in depolarization.
