  • Volume of the solute  + (Most of the chemicals for SUIT protocol tiMost of the chemicals for SUIT protocol titrations are prepared by weighing the substance on the balance, transferring to a volumetric glass flask and adding solvent until the intended volume is reached. However, for practical reasons some of the chemical compounds are prepared by just adding the solvent instead of adjusting it's volume. For example, this approach is useful if the substance is very toxic. Then an arbitratry amount is taken, its mass determined on the balance without trying to reach a specific value and the necessary amount of solvent is added. Adding the solvent instead of adjusting its volume is also useful if small amounts are needed (e.g. 1 mL) or if the compound has to be prepared directly before using it like Pyruvate. In these cases the volume contributed by the solute was tested.lume contributed by the solute was tested.)
  • Carrier control titrations  + (Most of the nonpolar compounds have to be Most of the nonpolar compounds have to be diluted in organic solvents such as DMSO or acetonitrile in order to use them for the titrations in the SUIT protocols. However, the solvent (carrier) itself could affect the mitochondrial physiology and promote alterations that we need to take into account. For this reason, it is necessary to run in parallel to our treatment experiment a control experiment on which we will add a '''carrier control titration''' to test if it affects our sample or not.' to test if it affects our sample or not.)
  • Q  + (Multiple meanings of Q ::::» [[Coenzyme Q]] Q ::::» [[Charge]] ''Q'', ''Q''<sub>el</sub> ::::» [[Heat]] ''Q'', ''Q''<sub>th</sub>)
  • Nigericin  + (Nigericin is a H<sup>+</sup>/KNigericin is a H<sup>+</sup>/K<sup>+</sup> antiporter, which allows the electroneutral transport of these two ions in opposite directions across the mitochondrial inner membrane following the K<sup>+</sup> concentration gradient. In the presence of K<sup>+</sup>, nigericin decreases pH in the mitchondrial matrix, thus, almost fully collapses the transmembrane ΔpH, which leads to the compensatory increase of the electric [[Mitochondrial membrane potential|mt-membrane potential]]. Therefore, it is ideal to use to dissect the two components of the [[Protonmotive force|protonmotive force]], ΔpH and [[Mitochondrial membrane potential|mt-membrane potential]]. It is recommended to use the lowest possible concentration of nigericin, which creates a maximal mitochondrial hyperpolarization. In the study of [[Komlodi 2018 J Bioenerg Biomembr]], 20 nM was applied on brain mitochondria isolated from guinea-pigs using 5 mM [[Succinate|succinate]] in the [[LEAK respiration|LEAK state]] which caused maximum hyperpolarisation, but did not fully dissipate the transmembrane ΔpH. Other groups (Selivanov et al 2008; Lambert et al 2004), however, used 100 nM nigericin, which in their hands fully collapsed transmembrane ΔpH using succinate as a respiratory substrate on isolated rat brain and skeletal muscle in the [[LEAK respiration|LEAK state]].AK respiration|LEAK state]].)

  • Nuclear receptors  + (Nuclear receptors are ligand-dependent transcription factors.)
  • Equivalence  + (Numerical '''equivalence''' (symbol ≡) indicates that two quantities are numerically equal, even if the full meaning may be different. For instance: 1 ≡ 1·1 and 1 ≡ 1/1. In contrast to ≡, the symbol = indicates physicochemical [[equality]].)

  • 2-Hydroxyglutarate  + (Reduction of [[oxoglutarate]]Reduction of [[oxoglutarate]] (2OG or alpha-ketoglutarate) to '''2-hydroxyglutarate''' (2HG) is driven by NADPH. 2HG is also formed in side reactions of [[lactate dehydrogenase]] and [[malate dehydrogenase]]. Millimolar 2HG concentrations are found in some cancer cells compared to , whereas side activities of lactate and malate dehydrogenase form submillimolar s-2-hydroxyglutarate (s-2HG). However, even wild-type IDH1 and IDH2, notably under shifts toward reductive carboxylation glutaminolysis or changes in other enzymes, lead to “intermediate” 0.01–0.1 mM 2HG levels, for example, in breast carcinoma compared with nanomolar concentrations in benign cells. 2HG is considered an important player in reprogramming metabolism of cancer cells. reprogramming metabolism of cancer cells.)
