Sodium–potassium pump - Wikipedia
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.
Sodium-Potassium Pump – Definition & Functions, with Diagram
Jul 19, 2021 · Sodium-Potassium Pump, also known as the Na + /K + pump or Na + /K +-ATPase, is a transmembrane protein pump found in animals’ cell (plasma) membrane. Its fundamental purpose is to transport sodium and potassium ions across the cell in the ratio of 3: 2.
Na + /K + -ATPase: More than an Electrogenic Pump - PMC
The sodium pump, or Na + /K +-ATPase (NKA), is an essential enzyme found in the plasma membrane of all animal cells. Its primary role is to transport sodium (Na +) and potassium (K +) ions across the cell membrane, using energy from ATP hydrolysis. This transport creates and maintains an electrochemical gradient, which is crucial for various ...

Mar 13, 2023 · Neurons need the Na, K ATPase pump to reverse postsynaptic sodium flux and re-establish the potassium and sodium gradients necessary to fire action potentials. Astrocytes also need Na, K ATPase pump to maintain the sodium gradient as the sodium gradient maintains neurotransmitter reuptake.
Sodium Potassium Pump: Structure, Mechanism, Function, and …
May 6, 2023 · The Sodium Potassium Pump / Na+ K+ pump is an electrogenic transmembrane ATPase that was discovered in 1957. It is found on the cytosolic side of the cells’ outer plasma membrane. For every ATP spent, the pump pumps 3 Na+ ions out of the cell and 2K+ ions in.
Structure and Function of Na,K-ATPase-The Sodium-Potassium …
Dec 29, 2021 · Na,K-ATPase is an ubiquitous enzyme actively transporting Na-ions out of the cell in exchange for K-ions, thereby maintaining their concentration gradients across the cell membrane. Since its discovery more than six decades ago the Na-pump has been studied extensively and its vital physiological rol …
A structural overview of the plasma membrane Na - Nature
Dec 22, 2010 · Crystal structures and functional studies of the Na +,K + -ATPase and the H + -ATPase have provided insight into their mechanisms of action in eukaryotic cells. Plasma membrane ATPases are...
The Structure and Function of the Na,K-ATPase Isoforms in …
The Na,K-ATPase in astrocytes with alpha2 and the beta2 subunit has relatively low potassium affinity and is suggested to be particularly important when the extracellular potassium concentration is high (Larsen et al., 2014).
The ATP-Dependent Na+,K+ Pump - Basic Neurochemistry - NCBI …
The principal primary active-transport system in neurons, as in most other animal cells, is a P-type pump that concurrently extrudes Na + and accumulates K +. For brevity, we will refer to it as the Na,K-ATPase. Depending on their functions, different tissues have vastly different requirements for pumping Na + and K +. Transport by Na,K-ATPases ...
Na+, K+-ATPase: Ubiquitous Multifunctional Transmembrane Protein and ...
The Na +, K +-ATPase (NKA) is an ubiquitous enzyme consisting of α, β and γ subunits, and is responsible for the creation and maintenance of the Na + and K + gradients across the cell membrane by transporting 3 Na + out and 2 K + into the cell.
