Video Summary:
Na-K ATPase pump actively transports Na out of the cell and K into the cell. During each cycle it moves 3 Na out, 2 K in and uses 1 ATP. The Na gradient established by this pump can be secondarily be used to transport other substances against their electrochemical gradient. By moving 1 net positive ion outside it creates electronegativity inside the cell. This is required for impulse transmission in neurons and muscles. And finally, it balances the ion entry driven by negatively charged proteins inside the cell, which contributes to maintain cell volume.
