ATPase pumps: NKE
======================================================================================
Sodium potassium exchanger
This transporter allows entry of two potassium ion in exchange for the extrusion of three sodium ions from the cell, at the expense of ATP being hydrolysed to release energy for the process. The bond-graph model is illustrated in the figure below, with the CellML model added for simulation purposes.

The bond graph representation of the six state NKE model.
After clicking the CellML file, the **Views Available** menu to the right provides various options to explore this model here in the Physiome Model Repository.
Of particular interest is the *Launch with OpenCOR* menu item, which will load the simulation experiment shown below directly into the `OpenCOR`_ desktop application.
