CI inhibitors like rotenone inhibit fatty acid oxidation (FAO)-linked respiration

Inhibition of CI leads to accumulation of NADH in the mt-matrix. The resultant lack of NAD⁺ blocks FAO.

Internal normalization of rate – what is the difference between flux control ratio and flux control efficiency?

A flux control ratio is the ratio of oxygen flux in a specific respiratory control state, normalized for maximum flux in a common reference state. Flux control efficiency expresses the control of respiration as a fractional change of oxygen flux or flow between protocol steps. Both values vary between theoretical lower and upper limits of 0 and 1.
