The dynamic model of interphase oxidation and phosphorylation with participation of membrane intermediate is considered. The feature offered L.-dependent of mechanism of interphase consists that, on the one hand, intermediate controls utilization of the protons by ATP-synthase, i.e. consumption delta microH+, and with other, - delta microH+ controls the work of respiratory chain, i.e. consumption of the substrate (respiratory control). In such model it is unlikely the appearance of futile cycle, i.e. condition dangerous for energetic, in which the speed of synthesis ATP and the speed of hydrolysis ATP in matrix are equal. Besides such system is very good adds glycolysis and is as appear, only by possible form of prolonged existence of energetic metabolism. The Mitchell model is considered as the particular case of integrated model. Is considered, that for mitochondria are real both model of interphase and the transition from one mechanism of interphase to is moreover possible other one. The transition to more simple (and less effective) model can be connected with some modification of ATP complex; this modification takes place probably at transition of cells to intensive division.
