Comments	Defining, and measuring, higher-plant respiration is difficult. Biochemically, respiration can be deined as the sum of glycolysis, the oxidative pentose phosphate pathway (or network), the tricarboxylic acid (TCA) or Krebs cycle, mitochondrial e- transport, oxidative phosphorylation, and intimately related reactions. A physiological definition of respiration is non-photorespiratory CO2 release (photorespiration being associated with photosynthesis), though photorespiration can contribute directly to mitochondrial e- transport.
