title: Temperature dependence of active K+ transport in cation dimorphic sheep erythrocytes.
abstract: Arrhenius diagrams of K+ pump fluxes measured between 15 degrees C and 41 degrees C were discontinuous in high K+ but not in low K+ sheep red cells. Exposure of low K+ cells to anti-L caused a bimodal temperature response of K+ pump flux with a transition temperature, Tc, similar to that found in high K+ cells but with comparatively higher activation energies above Tc.
