How is the conversion of energy released during the reactions of the oxygen phase of energy metabolism going? Compare the number of ATP molecules formed as a result of cyclic reactions and on the respiratory chain. Explain this fact

Energy is used to break down polymers to monomers (nucleic acids to nucleotides, proteins to amino acids, fats to glycerol and carboxylic acids), which will then participate in other stages of cellular respiration.
In the preparatory phase, ATP is not stored but dissipated in the form of heat. In the anoxic phase, 2 ATP molecules are formed, and in the oxygen phase 36 ATP molecules. Those. as a result of cellular respiration, only 38 ATP molecules are formed (2 molecules at the anaerobic stage and 36 at the aerobic stage).
