comparisons of mg2+/atp-driven 45ca2+ uptake and [ 14c ] scn-uptake with respect to the mg2+/atp concentration dependence , the effects of inhibitors , and the nucleotide and divalent cation specificities indicate that the energy for ca2+ accumulation is derived from atp hydrolysis catalyzed by the electrogenic plasma membrane atpase .
