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.
The sodium-potassium pump usually pumps?
potassium ions into the cell
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.
Which molecule is directly required for operation of the sodium-potassium pump?
ATP
What is 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.
In active transport carrier proteins?
sodium-potassium pump.
Does facilitated transport have a sodium potassium pump?
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated 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.
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Most animal cell membranes have proteins that pump ______ ions out of the cell and potassium ions into the cell
When the proteins of the sodium potassium pump are first synthesized in the rough ER what side of the ER?
It will be on the cytoplasmic side of the ER
What provides energy to run sodium potassium pump?
ATP provides the energy for the sodium potassium pump.
What would happen to the rate of ion transport if you increased the number of sodium-potassium pump proteins?
the transport will speed up
Through what type of proteins does active transport occur?
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
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.
