Transformations of metabolic organization are considered as a ground of structure generation during ontogenesis and evolution. The emergence of non-linearity in metabolic pathways which leads to the formation of biochemical cycles is caused by the separation between the direct and reverse enzymatic reactions, one of them being coupled with the pool of macroergs, whereas the other--non-coupled. The absence of couplings in one of the halves of such primary cycle can lead to the increase of metabolic flow and to the generation of bifurcations resulting in the formation of new metabolic pathway. For their internalization the genetic reconstructions are necessary. Deposition of compounds from the cycles leads to the generation of internal rhythms and to morphogenetic processes. Morphology is formed by stable trajectories of the formation and deposition of certain compounds according to the principles of curvilinear symmetry.
代谢组织的转变被认为是个体发育和进化过程中结构生成的基础。代谢途径中非线性的出现导致生化循环的形成,这是由直接和逆向酶促反应之间的分离引起的,其中一个反应与高能物质池耦合,而另一个反应则不耦合。这种初级循环的一半中缺乏耦合可能导致代谢流增加并产生分支,从而形成新的代谢途径。为了使其内化,基因重组是必要的。循环中化合物的沉积导致内部节律的产生和形态发生过程。形态是由某些化合物根据曲线对称原理形成和沉积的稳定轨迹形成的。
