-ATPase
(
sodium

potassium
adenosine
triphosphatase
, also known as the
pump
or
sodium-potassium pump
) is an
enzyme
(an electrogenic
transmembrane
ATPase
) found in the
plasma membrane
of all
animal
cells. The -ATPase enzyme is a
solute pump
that pumps sodium out of cells while pumping potassium into cells, both against their
concentration gradients
. This pumping is active (it uses energy from
ATP
) and is important for cell physiology. An example application is nerve conduction.
