P/E control ratio

Description

The OXPHOS control ratio, P/E, increases from a minimum of L/E if the capacity of the phosphorylation system is zero, to the maximum of 1.0 if the capacity of the phosphorylation system fully matches the ETS capacity (or in fully dyscoupled mitochondria), when there is no limitation of P by the phosphorylation system or the proton backpressure. It is important to separate the effect of ADP limitation from limitation by enzymatic capacity at saturating ADP concentration (Pesta_2010_Protocols).

Abbreviation: P/E
