Uncoupling-control ratio

Description

The uncoupling control ratio, UCR, is the ratio of ET-pathway/ROUTINE respiration (E/R) in intact cells, evaluated by careful uncoupler titrations (Steinlechner et al 1996). Compare ROUTINE control ratio (R/E) (Gnaiger 2008).

Abbreviation: UCR

Reference: Steinlechner-Maran 1996 Am J Physiol Cell Physiol

Biochemical coupling efficiency: from 0 to <1
