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.


What is the sodium-potassium pump?

the sodium-potassium pump is one of the most important carrier proteins in the animal cell.


The sodium-potassium pump usually pumps?

potassium ions into the cell


How does the sodium potassium pump operates?

The sodium-potassium pump functions much like a revolving door. Its main job is to keep sodium ions (NA+) outside of the cell and keep potassium ions (K+) inside of the cell. With the addition of energy from an ATP molecule, the sodium potassium pump moves three sodium ions out of the cell and moves two potassium ions into the cell with each turn. The goal of this process is to return, or keep, the cell at a resting state, or resting potential.


What do sodium potassium pumps pump?

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.

What type of active transport pump helps muscle cells contract?

the sodium potassium pump.


What characterizes the sodium-potassium pump?

The sodium-potassium pump is extremely important, especially in your nerve cells (neurons). The pump has 3 binding cites for sodium ions, and 2 binding cites for potassium ions. It uses these binding cites to pump sodium to the outside of a membrane and potassium to the inside. This an example of using ATP (energy) to go against the concentration gradient.
