Query: A mathematical model of the metabolism of a cell. Self-organization and
  chaos   Using the classical tools of nonlinear dynamics, we study the process of
self-organization and the appearance of the chaos in the metabolic process in a
cell with the help of a mathematical model of the transformation of steroids by
a cell Arthrobacter globiformis. We constructed the phase-parametric diagrams
obtained under a variation of the dissipation of the kinetic membrane
potential. The oscillatory modes obtained are classified as regular and strange
attractors. We calculated the bifurcations, by which the self-organization and
the chaos occur in the system, and the transitions "chaos-order",
"order-chaos", "order-order", and "chaos-chaos" arise. Feigenbaum's scenarios
and the intermittences are found. For some selected modes, the projections of
the phase portraits of attractors, Poincar\'e sections, and Poincar\'e maps are
constructed. The total spectra of Lyapunov indices for the modes under study
are calculated. The structural stability of the attractors is demonstrated. A
general scenario of the formation of regular and strange attractors in the
given metabolic process in a cell is found. The physical nature of their
appearance in the metabolic process is studied.
