The sodium-potassium pump (PDB entries 2zxe and 3b8e ) is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.

The sodium-potassium pump usually pumps?
potassium ions into the cell
What is the sodium-potassium pump?
the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
What is a sodium-ion pump?
The sodium pump is actually known as the sodium potassium pump. Most cells in the body need to contain a higher concentration of potassium ions (K+) than their environment. They also need to contain a lower number of sodium ions (Na+) than their environment. To achieve this the cell constantly pumps sodium ions out and potassium ions in. This requires energy, and therefore is called active transport. This is carried out by transporter proteins in the plasma membrane, working with ATP which supplies the energy. The ATP changes the shape of the transporter protein, the shape change moves 3 sodium ions out of the cell and 2 potassium ions in. This is called the sodium potassium pump.
Where does the sodium potassium pump move sodium and potassium to?
The sodium-potassium pump uses ENERGY to move ions, it is a form of active transport. It moves sodium ions, generall highly concentrated outside the cell, to the outside, and potassium ions highly concentrated within the cell, within. Thus, it moves ions from areas of low concentration to high concentration, a process unlike diffusion and osmosis.....it requires ATP or the energy currency of a cell.
The sodium-potassium pump transports what?
Na+ out of the cell and K+ into the cell
The sodium-potassium pump usually pumps?
potassium ions into the cell
What is a brief description of the action of the sodium-potassium pump?
The sodium-potassium pump is a transmembrane protein in a cell membrane. It keeps large concentrations of sodium ions outside the cell, and potassium ions inside the cell. It does this by pumping the sodium ions out, and the potassium ions in.
Is the Sodium Potassium pump located on the apical membrane?
Sodium Potassium pumps are located on your body cells. This pump is used as a type of active transport to let these ions into and out of your cell.
What is the effect of decreasing the number of sodium potassium pumps?
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport
Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
What does the sodium-potassium exchange pump transfer into and out of the cell during depolarization?
The sodium potassium pump does not function during depolarization, but rather after repolarization. During repolarization, potassium ions flow out of the cell into the extracellular space to reestablish membrane polarity. What the sodium potassium exchange pump does is reestablish the initial ionic concentrations. It does this by exchanging three sodium ions inside the cell for every two potassium ions outside the cell.
Why does water follow sodium and not potassium in the human body particularly in the kidney nephrons?
It follows both ... but sodium pumps are more common in your body.The only potassium pump I know of is in the kidneys - and is used for osmotic control.
What provides energy to run sodium potassium pump?
ATP provides the energy for the sodium potassium pump.
How does sprinting increase the sodium potassium pump efficiency?
Im not a very fast or strong person but I have noticed when a male/female sprints the sodium potassium pumps efficiency almost doubles from another who doesnt run daily.
