| Popis: | In this work, a mathematical model of self-oscillatory dynamics of the metabolism in a cell is studied. The full phase-parametric characteristics of variations of the form of attractors depending on the dissipation of a kinetic membrane potential are calculated. The bifurcations and the scenarios of the transitions {\guillemotleft}order-chaos{\guillemotright}, {\guillemotleft}chaos-order{\guillemotright} and {\guillemotleft}order-order{\guillemotright} are found. We constructed the projections of the multidimensional phase portraits of attractors, Poincar\'e sections, and Poincar\'e maps. The process of self-organization of regular attractors through the formation torus was investigated. The total spectra of Lyapunov exponents and the divergences characterizing a structural stability of the determined attractors are calculated. The results obtained demonstrate the possibility of the application of classical tools of nonlinear dynamics to the study of the self-organization and the appearance of a chaos in the metabolic process in a cells.
