Explanation:The Na + /K + -ATPase helps maintain resting potential, It also functions as a signal transducer/integrator to regulate the MAPK pathway, ROS, as well as intracellular calcium.
Explanation: II) Na+–K+–AT is covalently modified by phosphorylation at Asp residues which causes a conformational change in the pump.
IV). It contributes to the excitation (action potential) produced by nerve cells through the transport of three sodium ions out of the nerve cell into the extracellular space and two potassium ions into the intracellular space from the extracellular space.
