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.
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.
The sodium-potassium pump is an active transport pump that helps move sodium ions out of the cell and potassium ions into the cell against their concentration gradients. This process requires energy in the form of ATP to pump the ions across the cell membrane. The sodium-potassium pump is essential for maintaining the cell's resting membrane potential and is involved in regulating cell volume and transmitting nerve impulses.
This process is called the sodium-potassium pump. It uses ATP to pump sodium ions out of the cell against their concentration gradient and pump potassium ions back into the cell against their concentration gradient. This mechanism helps maintain the appropriate balance of sodium and potassium ions inside and outside the cell, which is crucial for cellular functions such as nerve transmission and muscle contraction.
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
The sodium-potassium exchange pump transfers 3 sodium ions out of the cell and 2 potassium ions into the cell during depolarization. This process helps in maintaining the electrochemical gradient across the cell membrane and is crucial for cell function.
In the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell. This movement is powered by ATP, which is hydrolyzed to provide the energy needed for the pump to function.
The sodium-potassium pump moves sodium ions out of the cell and potassium ions into the cell. The pump functions using energy from ATP hydrolysis. The pump maintains the chemical and electrical gradients of sodium and potassium ions across the cell membrane. The pump is found only in prokaryotic cells and not in eukaryotic cells.

NaKATPase transports 3 K ions into the cell and takes only two Na ions out of it.
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.
Active transport, specifically the sodium-potassium pump, helps human cells maintain their sodium and potassium concentrations. This pump actively moves three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients, using ATP for energy. This process is essential for maintaining cell volume and proper electrical potential across the cell membrane.
Positively charged ions like sodium (Na+) and potassium (K+) can cross back and forth across the neuron cell membrane through ion channels. These ions play a significant role in generating and propagating action potentials in neurons.
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.
Potassium enters the cell through potassium channels that open in response to changes in membrane potential. Sodium enters the cell through sodium-potassium pumps, which actively transport sodium ions against their concentration gradient.
