How many potassium ions does the sodium-potassium pump move into a cell if it moves six sodium ions out of the cell?

I think you're looking for three ... over the long run. But the trick is that K+ doesn't need to be pumped in. Membrane proteins act as variable sized pore in the membrane (channels) and the potassium flows in under electrostatic forces ... all the work is done pumping the Na+ out.

At the start of the action potential, during depolarisation of the axon membrane Sodium ions DIFFUSE into the axon. During repolarisation, Potassium ions DIFFUSE out of the axon.
During the period of refraction, Sodium ions are ACTIVELY PUMPED out of the axon and Potassium ions are ACTIVELY PUMPED into the axon.

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.
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.
The sodium-potassium pump releases?
Hmm. Maybe Sodium and Potassium? Or another answer is it transfers Na+ (sodium) out of the cell and K+ potassium into the cell.
Active transport pump that helps move materials form low to high concentrations?
Thesodium-potassium pump uses active transport to move 3 sodium ions to the outside of the cell for each 2 potassium ions that it moves 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.
What kinda ions are positively charged and can cross back and forth across the neuron cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.

What does the Na1 Ka1ATPase transport sodium and potassium into a cell sodium and potassium out of a cell sodium into cell potassium out of cell sodium out of cell potassium in ATP?
NaKATPase transports 3 K ions into the cell and takes only two Na ions out of it.
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.

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 prevents the accumulation of?
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
How do sodium and potassium travel into and out of cells?
The sodium potassium pump transports sodium and potassium into and out of the cell. look at this site. it will explain. Source: http://highered.mcgraw-hill.com/olcweb/cgi/pluginpop.cgi?it=swf::535::535::/sites/dl/free/0072437316/120068/bio03.swf::Sodium-Potassium%20Exchange%20Pump
Why are sodium potassium pumps important?
They regulate sodium and potassium in your cells. If they fail the sodium rushes in. Water follows sodium and too much water in a cell causes the cell to rupture and die.
