Kinetic model of water and urea permeability regulation by vasopressin in collecting duct

The urea and water transport pathways are monitored by certain physical processes, which provide information to study the theoretical approach of the process. A chaotic kinetic behavior is hypothesized by two- and three-state kinetic models of the apical membrane permeability activation and inactivation. The presumed controlling of the rate constants by vasopressin influences the activation and inactivation of the kinetics.
