  • Normalization of rate  + ('''Normalization of rate''' (respiratory r'''Normalization of rate''' (respiratory rate, rate of hydrogen peroxide production, growth rate) is required to report experimental data. Normalization of rates leads to a diversity of formats. Normalization is guided by physicochemical principles, methodological considerations, and conceptual strategies. The challenges of measuring respiratory rate are matched by those of normalization. Normalization of rates for: (''1'') the number of objects (cells, organisms); (''2'') the volume or mass of the experimental sample; and (''3'') the concentration of mitochondrial markers in the instrumental chamber are sample-specific normalizations, which are distinguished from system-specific normalization for the volume of the instrumental chamber (the measuring system). Metabolic ''flow'', ''I'', per [[Count |countable]] object increases as the size of the object is increased. This confounding factor is eliminated by expressing rate as sample-mass specific or sample-volume specific ''flux'', ''J''. [[Flow]] is an [[extensive quantity]], whereas [[flux]] is a [[specific quantity]]. If the aim is to find differences in mitochondrial function independent of mitochondrial density, then normalization to a [[mitochondrial marker]] is imperative. [[Flux control ratio]]s and [[flux control efficiency |flux control efficiencies]] are based on internal normalization for rate in a reference state, are independent of externally measured markers and, therefore, are statistically robust. and, therefore, are statistically robust.)
