<prompt> True regarding Na K pumpHetrodimer homogenousHetrodimer heterogenousHomodimer heterogenousHomodimer homogenous  <response>: Structure of NaK pump2 subunits- α subunit is larger and β subunit is smaller. Hence it is Heterodimer.α subunits- α1, α2 α3 isoforms.β subunits- β1, β2 β3 isoforms. Hence it is heterogeneous.
