Question

Explain the Na* and K* pump in cell membranes​

Answer 1

$\huge\tt\red{\underline{Answer}}$

Sodium-Potassium Pump also known as the Na+/K+ pump or Na+/K+-ATPase, this is a protein pump found in the cell membrane of neurons (and other animal cells). It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in. In the process, the pump helps to stabilize membrane potential, and thus is essential in creating the conditions necessary for the firing of action potentials.
