Transformations of metabolic organization are considered as a ground o
f structure generation during ontogenesis and evolution. The emergence
of non-linearity in metabolic pathways which leads to the formation o
f biochemical cycles is caused by the separation between the direct an
d reverse enzymatic reactions, one of them being coupled with the pool
of macroergs, whereas the other - non-coupled. The absence of couplin
gs 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 th
e cycles leads to the generation of internal rhythms and to morphogene
tic processes. Morphology is formed by stable trajectories of the form
ation and deposition of certain compounds according to the principles
of curvilinear symmetry.
