Med na k+ pumpen menas Natrium-kaliumpumpen är en proteinpump i djurs cellmembran som bidrar till att natrium har en högre koncentration utanför cellen än innanför, och kalium vice versa. Genom att använda sig av aktivtransport, kan proteinet flytta ut tre natriumjoner (Na+) och in två kaliumjoner (K+). 1 natrium, kalium balans 2 The sodium–potassium pump (sodium–potassium adenosine triphosphatase, also known as Na⁺/K⁺-ATPase, Na⁺/K⁺ pump, or sodium–potassium ATPase) is an enzyme (an electrogenic transmembrane ATPase) found in the membrane of all animal cells. It performs several functions in cell physiology. 3 natrium kalium pumpen hjärtat 4 The pump, which has adenosine-triphosphatase (ATPase) activity, traverses the cell membrane and is activated by external [K+] and internal [Na+]. This enzyme uses metabolic energy to transport (pump) Na+ outward and K+ inward. 5 muscle pump compression of veins by the contraction of skeletal muscles, forcing blood towards the heart against the flow of gravity; seen particularly in the deep veins of the lower limbs. Called also venous pump. Na+-K+ pump sodium-potassium pump. 6 The purpose of the sodium-potassium pump is to maintain the proper concentration of potassium ions K + and sodium ions Na + inside and outside of the cell. In the image below, you can see the pump. 7 na k pump 3 in 2 out 8 Natrium-kaliumpumpen är. 9 Na-K-pumpar kompenserar läckaget genom att aktivt pumpa in kalium. 10 Na-K pump - definition. also known as the sodium-potassium pump or Na+/K+-ATPase, this is a protein pump found in the cell membrane of neurons (and other animal cells). It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in. 11
