Fig. 7. Arrhenius plots showing Na+/K+-ATPase maximal
activity as a function of temperature (Kelvin) for (A) foot muscle and (B)
hepatopancreas from O. lactea. Values are means ± s.e.m.,
N=4 independent preparations of enzyme. Assay mixtures were
pre-incubated for 5 min in water baths set to specified temperatures prior to
initiating reactions by the addition of Mg2+.ATP. Assays were
conducted at maximal substrate concentrations. Arrhenius activation energy
(EA) was calculated from the linear part of the
graphs.
