sodium-potassium pump

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

The sodium-potassium pump has been shown to control and set the intrinsic activity mode of Purkinje cells.

See: Sodium-Potassium Pump where the transport ratio would be 2/3.

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

The action of the sodium-potassium pump is not the only mechanism responsible for the generation of the resting membrane potential.

Thermogenesis can also be produced by leakage of the sodium-potassium pump and the Ca pump.

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

In exchange, the organism pumps sodium (Na) ions out with the help of the sodium-potassium pump.

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

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

Active transport via sodium-potassium pump action moves salt from the blood into the gland, where it is excreted as a concentrated solution.

As ischemia occurs through inhibition of the sodium-potassium pump, abnormalities in the threshold potential are hence implicated.

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

Physiologically, inhibition of the sodium-potassium pump generally causes diarrhea, as it prevents water reabsorption from the intestines.

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

It also hyperpolarizes the cell membrane through influencing the sodium-potassium pump and thereby rendering it less responsive to adrenergic stimulation.

The sodium-potassium pump was identified in 1957 and its properties gradually elucidated, culminating in the determination of its atomic-resolution structure by X-ray crystallography.

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

The ion pump most relevant to the action potential is the sodium-potassium pump, which transports three sodium ions out of the cell and two potassium ions in.

This process, called active transport, get its energy from ATP and other ATP-related cotransport systems that produce energy, like the sodium-potassium pump.

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.

Ustalic acid is an inhibitor of the sodium-potassium pump (Na/K-ATPase), found in the plasma membrane of all animal cells.

Nobelprize.org - Jens C. Skou's Nobel Lecture on "The Identification of the Sodium-Potassium Pump"

The sodium-potassium pump was discovered in the 1950s by a Danish scientist, Jens Christian Skou, who was awarded a Nobel Prize in 1997.

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.
