Box whisker plots of mitochondrial enzyme activities in liver segments IV and VII.

The plots demonstrate the distribution of enzyme activities round the median in each segment, shown before and after 4-hr preservation. The enzyme activities were not significantly different between segments IV and VII (p > 0.05). The activities of citrate synthase, aconitase, complex I-III are expressed in nmol/mg/min while the activity of complex IV is expressed in k/mg/min. Top and bottom whiskers represent the maximum and minimum values, respectively. Circles represent outliers (1.5 to 3x interquartile range) and diamonds represent extreme outliers (> 3x interquartile range).
