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 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.
What ions are pumped in and out of cell through the sodium potassium pump?
3 sodium ions go out and 2 potassium ions go in
Do ions need a transport protein to enter bilayer?
Yes! K+ or Na+ or exchanged with its specific potassium and sodium pump protein on the membrane.
In a sodium-potassium pump what molecules are moved and where are they moved to?
In a sodium-potassium pump a carrier protein uses ATP in Active transport. The sodium ions are transported out of the cells and the potassium ions are transported into the cell.
The sodium-potassium pump usually pumps?
potassium ions into the cell
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
What type of ions does the sodium-potassium pump pick up on the outside of the cell?
Sodium ions
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.
The sodium-potassium pump uses no energy to function?
Using energy supplied by ATP, sodium ions are constantly pumped out of the nerve cell while at the same time potassium ions are pumped into the cell. This is termed the sodium-potassium pump.
Period during which potassium ions diffuse out of the neuron's membrane?
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.
