Extensive quantity

Description

Extensive quantities pertain to a total system, e.g. oxygen flow. An extensive quantity increases proportional with system size. The magnitude of an extensive quantity is completely additive for non-interacting subsystems, such as mass or flow expressed per defined system. The magnitude of these quantities depends on the extent or size of the system (Cohen et al 2008).

Normalization of rate. (A) Cell respiration is normalized for (1) the experimental Sample (flow per object, mass-specific flux, or cell-volume-specific flux); or (2) for the Chamber volume. Flow per object and flow per system are extensive quantities. From Gnaiger 2019 MitoFit Preprints.
