The potential of the reference electrode is constant. The other electrode is called the indicator electrode. If this is an ion-selective electrode which is in equilibrium with the solution, the measured electric potential difference is proportional to the (negative) logarithm of the activity of a specific ion in the solution. Examples are the pH glass electrode for measurement of pH, and the TPP+ electrode for measurement of pTPP and calculation of mt-membrane potential.ment of pTPP and calculation of mt-membrane potential.)

Precision + ('''Precision of measurement''' is the clos … '''Precision of measurement''' is the closeness of agreement between independent results of measurements obtained under stipulated conditions [SOURCE: ISO 3534-1:1993, 3.14]. Precision of measurement cannot be given a numerical value in terms of the [[measurand]], only descriptions such as 'sufficient' or 'insufficient' for a stated purpose. The degree of precision is usually expressed numerically by the statistical measures of imprecision of measurements, such as standard deviation and coefficient of variation, that are inversely related to precision. "Precision" of a given measurement procedure is subdivided according to the specified precision conditions. "[[Repeatability]]" relates to essentially unchanged conditions and is often termed "withinserial" or "within-run precision". "[[Reproducibility]]" relates to changes in conditions, e.g. time, different laboratories, operators, and measuring systems (including different calibrations and reagent batches).fferent calibrations and reagent batches).)

Pressure + ('''Pressure''' is a fundamental quantity e … '''Pressure''' is a fundamental quantity expressing energy per volume. The SI unit of pressure is generally pascal [Pa] = [J·m-3]. The term 'stress' (mechanical stress) is used as a synonym for pressure ([[Bureau International des Poids et Mesures 2019 The International System of Units (SI) |SI]]). Pressure is known in physics as mechanical pressure, which is force per area, ''p'' = ''F''·''A''-1 [Pa] = [N·m-2]. In physical chemistry, gas pressure is defined as ''p'' = ''n''·''V''-1·''RT'', where the [[concentration]] is ''c'' = ''n''·''V''-1 [mol·m-3], ''R'' is the [[gas constant]], and ''T'' is the absolute temperature, and ''RT'' is expressed in units of chemical force [J·mol-1]. van't Hoff's osmotic pressure assumes the same form applied to dissolved substances diffusing across a semipermeable membrane, but concentrations should be replaced by [[activity |activities]]. The activity of dissolved gases is expressed by the [[partial pressure]], where the [[solubility]] can be seen as an activity coefficient. Pressure appears explicitely or implicitely in all chapters of physics and physical chemistry. In contrast to the universal counterparts energy and force, however, the general connections between various isomorphic expressions of pressure remain poorly understood: Pressure is the concentration of the [[force]] at the point of [[action]]. More generally, pressure is the force times concentration at the interphase of interaction.]]. More generally, pressure is the force times concentration at the interphase of interaction.)

Slip is different from the [[proton leak]], which depends on Δ''p'' and is a property of the inner mt-membrane (including the boundaries between membrane-spanning proteins and the lipid phase). Slip is an uncoupling process that depends mainly on flux and contributes to a reduction in the [[biochemical coupling efficiency]] of ATP production and oxygen consumption. Together with proton leak and cation cycling, proton slip is compensated for by [[LEAK respiration]] or LEAK oxygen flux, ''L''. Compare: [[Proton leak]].[Proton leak]].)

Publication efficiency ''F''r,a/p = ''F''r/p·''F''a/p is low due to (''1'') the reproducibility crisis expressed as low reproducibility efficiency ''F''r/p = ''N''r/''N''p, and (''2'') the inflation crisis expressed as low attention efficiency ''F''a/p = ''N''a/''N''p. Estimates of these partial efficiencies vary from field to field. With ''F''r/p=0.15 and ''F''a/p=0.05, the current publication efficiency is as low as 0.0075, or only 0.75 % of all presently published communictions are reproducible and receive attention and meaningful interpretation. Reduction of the number of irreproducible zero-value publications is the most effective measure to reduce the paper mass excess (PME) in the reproducibility-inflation (R&I)-crisis.

Q-cycle + ('''Q-cycle''' refers to the sequential oxi … '''Q-cycle''' refers to the sequential oxidation and reduction of the electron carrier Coenzyme Q (CoQ or [[ubiquinone]]) in mitochondria or plastoquinones in the photosynthetic system. Originally, the concept of the Q-cycle was proposed by [[Mitchell P|Peter D Mitchell]]. Following several modifications, the Q-cycle is established, describing how [[CIII]] translocates hydrogen ions against the protonmotive force. The reduced CoQ ([[quinol |ubiquinol]] QH2) binds to the Qo site of CIII, while the oxidized CoQ ([[ubiquinone]] Q) to the Qi site of CIII. First, QH2 reduces the iron-sulfur protein and feeds cytochrome ''c''1 with one electron. The other electron is transferred to the ''b''L heme and reduces the ''b''H heme, which transfers the electron to ubiquinone at the Qi-site which is reduced to a [[semiquinone]]. A second QH2 is required to fully reduce semiquinone to ubiquinol. At the end of the Q-cycle, four protons leave the mt-matrix and enter the intermembrane space, and the reduced cytochrome ''c'' transfers electrons to CIV. The ubiquinol generated at the Qi-site can be reused by binding to the Qo-site of CIII.chrome ''c'' transfers electrons to CIV.
