Description
Respiratory oxygen flow is the oxygen consumption per total system, which is an extensive quantity. Flow is advancement of a transformation in a system per time [mol·s-1], when 'system' is defined as the experimental system (e.g. an open or closed chamber). Flow is distinguished from the size-specific quantity flux obtained by normalization of flow per volume of the experimental system [mol·s-1·m-3]. An experimental object, e.g. a living cell, may be considered as the 'experimental system'. Then oxygen flow per cell has the unit [mol·s-1·x-1], where [x] is the elementary unit for a count. Oxygen flow or respiration per cell [amol·s-1·x-1] = [pmol·s-1·Mx-1] is normalized for the cell count, distinguished from oxygen flux (e.g. per mg protein or wet mass). These are different forms of normalization of rate.
Abbreviation: IO2 [mol·s-1] or [mol·s-1·x-1]
