Description
The LEAK control ratio, or L/E coupling control ratio [1,2], is the flux ratio of LEAK respiration over ET capacity, as determined by measurement of oxygen consumption in sequentially induced states L and E of respiration. The ET-pathway control ratio is an index of uncoupling or dyscoupling at constant ET capacity. L/E increases with uncoupling from a theoretical minimum of 0.0 for a fully coupled system, to 1.0 for a fully uncoupled system [3].
