Application of petri nets methodology to determine biophysicochemical parameters of mitochondria functioning

Abstract

With the use of Petri net methodology a mathematical simulation model able to predict simultaneous changes in biophysicochemical parameters of mitochondria functioning was developed. the model allowed to interconnect in time the changes in mitochondria hydrodynamic diameter, electronic transport chain functioning, endogenous fluorescence of adenine nucleotides, DCF fluorescence signal of ROS production and NaN 3 effects. It was shown that the calculated values of the studied biophysicalchemical parameters correspond to those obtained experimentally. the model permit to link mitochondrial functional changes and their structural representation and to optimize significantly experimental procedures.
