Coenzyme Q - a mobile redox compound in the electron transfer system
Coenzyme Q is a lipid composed of a benzoquinone ring with an isoprenoid side chain, two methoxy groups and one methyl group being present in all tissues and cells. In humans, CoQ10 occurring in the mitochondrial electron transfer system transfers electrons from dehydrogenases and respiratory complexes downstream to Complex III.

TPP+ for potentiometric detection of mt-membrane potential (mtMP) or fluorometry with safranin?
Safranin enables measurement of the relationship between fluorescence intensity and mtMP, and if linear, the absolute mtMP can be calculated. TPP+ enables calibration for measurement of mtMP.

Do you know how to select the correct fluorescence sensors and filter set?
Using different fluorescence sensors, LED and photodiode filters, the O2k-Fluo Smart-Module (or O2k-Fluo LED2-Module) enables measurement of hydrogen peroxide, ATP, mitochondrial membrane potential, calcium, and numerous other applications open for O2k-user innovation.

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.

Measuring fatty acid oxidation (FAO)-linked respiration requires a low concentration of malate
In the absence of malate, accumulation of Acetyl-CoA inhibits FAO.
