[The information content of intracellular water and its accumulation in embryo- and phylogenesis (author's transl)].

The nucleo-free erythrocytes is presented as the simplest differentiated cell whose energy-exchange has the single purpose of preserving the cell structure; this structure is based on the regular quasi-crystalline state of intracellular water, which is expressed by the negative entropy (-SW) and the temperature TW which is higher than the temperature of the extracellular water T. The information content of intracellular water, JW is proportional to the temperature difference: JW approximately delta T = TW - T. The regular state of intracellular water is maintained by the basal metabolism that takes place in the membrane of the differentiated cell.

[Temperature-dependence of biological process (author's transl)].

Temperature dependence of biological processes is described by the modified Arrhenius equation, in which the constant is replaced by a temperature-variable coefficient. The theoretical foundation for this replacement is given and experimentally verified.

[The hemoglobin molecule from a cybernetic and thermodynamic point of view (author's transl)].

The biological macromolecule hemoglobin (Hb) represents a reversibly functioning molecular machine. The Hb molecule is engaged in inner or structural work, which is cyclic in nature and is regulated through an exchange with the external milieu, of warmth and matter. The endothermic process of deoxygenation requires an external milieu that gives off warmth and that absorbs oxygen; the exothermic process of oxygenation, on the other hand, requires an external milieu that absorbs warmth and gives up oxygen.
