[Relationship between energetics and reduction level of organic substances as an important factor in metabolic energy balance].

The reduction level of any chemical compounds is measured by special units--redoxones. In organic compounds the energetic value of redoxon is almost constant. Application of this concept makes it possible to simplify considerably the energetic calculations in biochemistry and to develop a common approach considering metabolism as the transfer of redoxons along the reactions network from the initial source of the redoxons to the biomass substance. Equations are presented for material-energetic balance of heterotrophic and autotrophic metabolism for the energetic yield of cell growth.
