title: An explanation of apparent sudden change in the activation energy of membrane enzymes.
abstract: If an enzyme-lipid mixture forms phases of pure lipid and enzyme-lipid solution, and enzyme activity depends on the composition of the enzyme-lipid solution, the temperature-dependence of lipid solubility in the enzyme-lipid solution leads to apparent sudden changes in enzyme activation energy without activity discontinuities at lipid phase transition temperatures.
