Na/K ATPase is essential in maintaining the electrochemical gradient across the cell membrane. The electrochemical gradient generated by transporting Sodium out and Potassium in is used in secondary active transport, maintanence of osmotic balance, and most importantly, action potential generation and propagation in muscle and nerve cells.

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
Can sodium still enter a membrane if ATP is not present to activate the sodium potassium pump?
no as there is no energy to form a conrormational change in the protein pump
The mechanism that prevents sodium ions from building up inside the cell is called?
I have a pretty strong hinch that it is Sodium potassium pump
What concentration gradients are established and maintained by the sodium-potassium exchange pump?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
Is it true that sodium-potassium pump ejects two Na from the cell and transports three K back into the cell in order to stabilize the resting membrane potential?
false
What is the sodium potassium pump?
the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
What is the sodium-potassium pump?
the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
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 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.
What provides energy to run sodium potassium pump?
ATP provides the energy for the sodium potassium 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.
What form of cellular transportation helps human cells maintain their sodium and potassium concentration?
The sodium/potassium pump, the sodium leak channel and the potassium leak channel.
Which ions are exchanged in a sodium potassium pump?
3 sodium ions for 2 potassium ions.
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.
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.
The sodium potassium pump prevents the accumulation of?
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
