Normally, sodium-potassium pumps in the membrane of cells ( in this case, cardiac myocytes ) pump potassium ions in and sodium ions out.

Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump.

The action of the sodium-potassium pump is an example of primary active transport.

A primary ATPase universal to all life is the sodium-potassium pump, which helps to maintain the cell potential.

* The pump for sodium and potassium is called sodium-potassium pump or Na < sup >+</ sup >/ K < sup >+</ sup >- ATPase

Na < sup >+</ sup >/ K < sup >+</ sup >- ATPase ( Sodium-potassium adenosine triphosphatase, also known as Na < sup >+</ sup >/ K < sup >+</ sup > pump, sodium-potassium pump, or sodium pump ) is an enzyme () ( an electrogenic transmembrane ATPase ) located in the plasma membrane of all animal cells.

The mechanism responsible for this is the sodium-potassium pump, which moves these two ions in opposite directions across the plasma membrane.

The sodium-potassium pump moves 3 sodium ions out and moves 2 potassium ions in, thus in total removing one positive charge carrier from the intracellular space.

Not only the mechanism of the sodium-potassium pump alone is responsible for the generation of the resting membrane potential.

The chief function of the inner segment is to provide ATP ( energy ) for the sodium-potassium pump.

ATP provided by the inner segment powers the sodium-potassium pump.

Denmark's first professor of sociology was a member of the faculty of Aarhus University ( Theodor Geiger, from 1938 – 1952 ), and in 1997 Professor Jens Christian Skou received the Nobel Prize in Chemistry for his discovery of the sodium-potassium pump.

However, in his paper he was wary of identifying the enzyme with the active ion movement, so he left out the term “ sodium-potassium pump ” from the title of his paper.

Ouabain did indeed inhibit the enzyme, thus establishing a link between the enzyme and the sodium-potassium pump.

Thermogenesis can also be produced by leakage of the sodium-potassium pump and the Ca < sup > 2 +</ sup > pump.

The sodium-potassium pump uses energy derived from ATP to exchange sodium for potassium ions across the membrane.

A major contribution to establishing the membrane potential is made by the sodium-potassium exchange pump.

The sodium-potassium exchange pump is relatively slow in operation.

This pump operates in a conceptually similar way to the sodium-potassium pump, except that in each cycle it exchanges three Na < sup >+</ sup > from the extracellular space for one Ca < sup >++</ sup > from the intracellular space.

Powered by a liquid sodium-potassium thermionic converter driven by a nuclear reactor containing around of Uranium 235, the satellite was intended for long-term on-orbit observation, but by December 1977 the satellite had deviated from its designed orbit and its flightpath was becoming increasingly erratic.

The eutectic sodium-potassium ( NaK ) alloy was used as a coolant in the SNAP-10A.

Digitalis works by inhibiting sodium-potassium ATPase.

In the case of the resting membrane potential across an animal cell's plasma membrane, potassium ( and sodium ) gradients are established by the Na +/ K +- ATPase ( sodium-potassium pump ) which transports 2 potassium ions inside and 3 sodium ions outside at the cost of 1 ATP molecule.

An important example is the sodium-potassium exchanger ( or Na < sup >+</ sup >/ K < sup >+</ sup > ATPase ), which establishes the ionic concentration balance that maintains the cell potential.

Such food staples have fundamentally altered several key nutritional characteristics of the human diet since the Paleolithic era, including glycemic load, fatty acid composition, macronutrient composition, micronutrient density, acid-base balance, sodium-potassium ratio, and fiber content.

The binding of two acetylcholine molecules results in a conformational change in the receptor that opens the sodium-potassium channel of the nicotinic receptor.

NaK, or sodium-potassium alloy, an alloy of potassium ( K ) and sodium ( Na ), is usually liquid at room temperature.

This carbine ( under $140, about $15 more for a deluxe grade ) has an 18-1/2-inch barrel and was obviously inspired by the popularity of last year's Model 760 pump with a short-barrel.

Up until recently, this heat pump method of warming air was efficient only in areas of mild winters and when outside temperatures were above 40 degrees.

It was originally named Antlia pneumatica (" Machine Pneumatique " in French ) to commemorate the air pump invented by the French physicist Denis Papin.

Spraying was usually done either from helicopters or from low-flying C-123 Provider aircraft, fitted with sprayers and " MC-1 Hourglass " pump systems and chemical tanks.

His twin-cylinder pump incorporated a crankshaft, but the device was unnecessarily complex indicating that he still did not fully understand the concept of power conversion.

Gaede used the name diffusion pump since his design was based on the finding that gas cannot diffuse against the vapor stream, but will be carried with it to the exhaust.

Eventually, by the end of December, after further modifications to her fuel system, and the repalcement of a fuel pump, the fuel starvation problem was fixed, and Campbell awaited better weather to mount an attempt.

Based on these descriptions and the Byzantine sources, John Haldon and Maurice Byrne reconstructed the entire apparatus as consisting of three main components: a bronze pump ( the σίφων, siphōn proper ), which was used to pressurize the oil ; a brazier, used to heat the oil ( πρόπυρον, propyron, " pre-heater "); and the nozzle, which was covered in bronze and mounted on a swivel ( στρεπτόν, strepton ).

The substance was pressurized by the heat and the usage of a force pump.

Hydraulic power networks also developed, using pipes to carrying pressurized water and transmit mechanical power from the source to end users elsewhere locally ; the power source was normally a head of water, which could also be assisted by a pump.

The first self-acting ram pump was invented by the Frenchman Joseph Michel Montgolfier ( best known as a co-inventor of the hot air balloon ) in 1796 for raising water in his paper mill at Voiron.

Radcliffe was able to hack the wireless interface used to control the pump remotely.

The steam engine was used to pump water from coal mines ; to lift trucks of coal to the surface ; to blow air into the furnaces for the making of iron ; to grind clay for pottery ; and to power new factories of all kinds.

He constructed and patented in London a low-lift combined vacuum and pressure water pump, that generated about one horsepower ( hp ) and was used in numerous water works and tried in a few mines ( hence its " brand name ", The Miner's Friend ), but it was not a success since it was limited in pumping height and prone to boiler explosions.

Another important invention, one which Watt was most proud of, was the Parallel motion which was essential in double-acting engines as it produced the straight line motion required for the cylinder rod and pump, from the connected rocking beam, whose end moves in a circular arc.

He avoided a large crash at the first corner and was running third towards the end of the race when the fuel pump mount failed.

Pulsed pumping was historically used with dye lasers where the inverted population lifetime of a dye molecule was so short that a high energy, fast pump was needed.

Another feature specifically intended to help out in cold conditions was a manual auxiliary fuel pump.
