Abstract: A previous critique of the term facultative invertebrate anaerobiosis focused on the duration of anoxia. An addition, important, yet much neglected aspect is dicussed here, namely the extent and quantification of the 'anaerobic' condition. • Keywords: CaloRespirometry, Twin-Flow

Selected quotes
- Still, mammalian biochemists are insufficiently aware of the importance of anaerobic mitochondrial energy transformation in metazoans, although ATP formation coupled to anaerobic mitochondrial electron transport occurs not only in invertebrates (Saz, 1981) but in mammalian myocyte mitochondria (Wiesner et al., 1988).
- In zoophysiology, 'anaerobic' (without air) is rarely defined in terms of controlled measurements of the actual extent of anaerobic conditions.
- Metabolic hypoxia is indicated as a reduced oxygen flux below the critical oxygen pressure (Figure 2) and is either fully or partially anaerobic.
- In a perfect conformer the relation between oxygen flux and pressure is not only linear but proportional (for a discussion of generalized flux-pressure relations, see Gnaiger (1989)).
- Microxic regulation .. effectively increases the slope of the flux-pressure relation in the microxic region.
- The slope of an ideal conformer is equivalent to a 5 % increase of oxygen flux per kPa (Figure 5a).
