| Abstract: | By using an LKB2277 Bioactivity Monitor system, the metabolic thermogenic curves of mitochondria isolated from M.m.albula liver tissue were determined, the M.m.albulas were incubated by the water with different concentration of NaF. The experimental results show that if the concentration of NaF was increased, the maximum heat power and heat output of metabolism increased, lag phase and activity maintain time were decreased. After the thermogenic curves had been determined, the ATP concentration of samples were determined, with the increasing of NaF concentration, ATP concentration decreased. Comparing the results of super\|microstructure of liver cell by TEM, basing on the chemical suspension theory, the experimental results were explained significantly. |
