oxidation — carbohydrates, fatty acids, amino acids, etc. Their degradation
can follow different pathways — glycolysis, the pentosophosphate cycle,
the Krebs cycle known as the cycle of tricarboxylic acids (Fig. 1–9) or in the
respiratory chains, but always accompanied with the formation of CO₂ and
H₂O as end products. The energy released is used for the synthesis of
ATP. These problems are a subject of any textbook in biochemistry and
that is why will be omitted.
