  On the basis of a mathematical model, we continue the study of the metabolic
Krebs cycle (or the tricarboxilic acid cycle). For the first time, we consider
its consistency and stability, which depend on the dissipation of a
transmembrane potential formed by the respiratory chain in the plasmatic
membrane of a cell. The phase-parametric characteristic of the dynamics of the
ATP level depending on a given parameter is constructed. The scenario of
formation of multiple autoperiodic and chaotic modes is presented. Poincar\'{e}
sections and mappings are constructed. The stability of modes and the
fractality of the obtained bifurcations are studied. The full spectra of
Lyapunov indices, divergences, KS-entropies, horizons of predictability, and
Lyapunov dimensionalities of strange attractors are calculated. Some
conclusions about the structural-functional connections determining the
dependence of the cell respiration cyclicity on the synchronization of the
functioning of the tricarboxilic acid cycle and the electron transport chain
are presented.
