E-P control efficiency

Description

The apparent excess E-P capacity factor (E-P coupling control factor), j_ExP = (E-P)/E = 1-P/E, is an expression of the relative limitation of OXPHOS capacity by the capacity of the phosphorylation system. j_ExP = 0.0 when OXPHOS is not limited by the phosphorylation system at zero Excess capacity, P=E, when the phosphorylation system does not exert any control over OXPHOS capacity. j_ExP increases with increasing control of the phosphorylation system over OXPHOS capacity. j_ExP = 1 at the limit of zero phosphorylation capacity. The OXPHOS state of mt-preparations is stimulated to ET-pathway by uncoupler titration, which yields the excess E-P capacity, ExP=E-P.
