Abstract: The metabolic thermogenesis curves of the metabolism of the mitochondria isolated from rice have been determined by using an LKB2277 Bioactivity Monitor. The thermodynamics and kinetics of the rice mitochondrial metabolism out of the cell have been studied. The metabolic thermogenesis curves of the rice mitochondria appeared four different phases. If the rice mitochondria have been laid up for different time, the metabolic thermogenesis curves and the kinetic behaviours of the rice mitochondria are different. Some thermodynamic values and kinetic paramters, as well as some new experimental thermokinetic equations in the activity increasing phase of the rice mitochondria,have been calculated and established.

Key words: microcalorimetry, thermochemistry, rice mitochondria, metabolism, thermokinetics
