[Comparative analysis of the mechanism of metabolism of storage compounds in the cell clock].
The effect of the autooscillation period Td of various kinetic mechanisms for D in equilibrium with S exchange (D storage form of the compound S) was theoretically studied in a system of the D in equilibrium with S in equilibrium with G1 type, where G = S in equilibrium with G1 is a relaxation autooscillator. The kinetics studied were linear, hyperbolic and cooperative. With a rapid D in equilibrium S exchange all the three kinetic mechanisms were shown to yield approximately equal values of Td. However, they greatly differ in energy losses for stray substrate recirculations in the D in equilibrium S cycle: the least losses were in the case of the cooperative kinetics and the greatest in that of the linear mechanism, while the hyperbolic mechanism yielded intermediate values. The results obtained hold for any energy-dependent mechanisms of D in equilibrium S synthesis and are independent of the specific pattern of the oscillator G.
