• Coupled respiration  + ('''Coupled respiration''' drives oxidative … '''Coupled respiration''' drives oxidative phosphorylation of the diphosphate [[ADP]] to the triphosphate [[ATP]], mediated by proton pumps across the inner mitochondrial membrane. Intrinsically [[uncoupled respiration]], in contrast, does not lead to phosphorylation of ADP, despite of protons being pumped across the inner mt-membrane. Coupled respiration, therefore, is the coupled part of respiratory oxygen flux that pumps the fraction of protons across the inner mt-membrane which is utilized by the phosphorylation system to produce ATP from ADP and Pi. In the OXPHOS state, mitochondria are in a partially coupled state, and the corresponding coupled respiration is the [[free OXPHOS capacity]]. In the state of ROUTINE respiration, coupled respiration is the [[free ROUTINE activity]].[[free ROUTINE activity]].)

In mitochondrial preparations, there are three well-defined coupling states of respiration: [[LEAK respiration]], [[OXPHOS]], and [[Electron transfer pathway |Electron-transfer-pathway state]] (ET state). In these states, the corresponding respirtory rates are symbolized as ''L'', ''P'', and ''E''. In living cells, the OXPHOS state cannot be induced, but in the [[ROUTINE]] state the respiration rate is ''R''. A reference rate ''Z'' is defined by taking ''Z'' as the maximum flux, i.e. flux ''E'' in the ET-state, such that the lower and upper limits of the ''CCR'' are defined as 0.0 and 1.0. Then there are two mitochondrial ''CCR'', [[L/E |''L/E'']] and [[P/E |''P/E'']], and two ''CCR'' for living cells, [[L/E |''L/E'']] and [[ROUTINE-control ratio |''R/E'']].[[ROUTINE-control ratio |''R/E'']].)
• Coupling-control state  + ('''Coupling-control states''' are defined … '''Coupling-control states''' are defined in [[mitochondrial preparations]] (isolated mitochondria, permeabilized cells, permeabilized tissues, homogenates) as [[LEAK respiration]], [[OXPHOS]], and [[ET-pathway |ET]] states, with corresponding respiration rates (''L, P, E'') in any [[electron-transfer-pathway state]] which is competent for electron transfer. These coupling states are induced by titration of ADP and uncouplers, and application of specific inhibitors of the [[phosphorylation pathway]]. In [[living cells]], the coupling-control states are [[LEAK respiration]], [[ROUTINE]], and [[ET pathway |ET]] states of respiration with corresponding rates ''L, R, E'', using membrane-permeable inhibitors of the [[phosphorylation system]] (e.g. [[oligomycin]]) and [[uncoupler]]s (e.g. [[CCCP]]).

• Electric current  + ('''Current''' or electric [[flow]] … '''Current''' or electric [[flow]] ''I''_el is the [[advancement]] of [[charge]] per unit of time, expressed in the SI base unit [[ampere]] [C·s^-1 = A]. Electrons or ions are the current-carrying [[motive entity |motive entities]] of electric flow. Electrons e^- are negatively charged subatomic particles carrying 'negative electricity' with a mass that is about 1/1700 of the smallest particle — the proton — carrying 'positive electricity' (Thompson 1906). Correspondingly the [[velocity]] of electrons is much higher than that of protons or any other (larger) ion. Current is the velocity ''v'' of paticles times the number of motive charges. Therefore, electron current ''I''_e^- is of a different nature from electric current ''I''_el''χ'' carried by all species ''i'' of ions ''X_i'' (cations and anions) summarized as ''χ'' = Σ(''z_i''·''X_i''). Whereas ''I''_e^- is the net translocation of electrons moving forwards and backwards, ''I''_el''χ'' is the net translocation of charges carried by different cations and anions. In contrast, ion current ''I''_elX of a specific ion X is the partial translocation of charges carried by net translocation of ion X only. If cation current ''I''_elX⁺ is antagonized entirely by counterion current ''I''_elY^- as the process of antiport, then the electric current ''I''_el''χ'' is zero. The (net) electric current in a compartmental system is driven by the electric force Δ_el''F''_p⁺ or electric potential difference Δ''Ψ''_p⁺, whereas a compensated ion/counterion antiport current is insensitive to the electric potential difference.tal system is driven by the electric force Δ_el''F''_p⁺ or electric potential difference Δ''Ψ''_p⁺, whereas a compensated ion/counterion antiport current is insensitive to the electric potential difference.)

In CV, the [[Q-Sensor]] with the [[three-electrode system]] is used to obtain information about the analyte ([[Coenzyme Q|CoQ]]) by measuring the current (''I'') as the electric potential (''V'') between two of the electrodes is varied. In CV the electric potential between the glassy carbon (GC) and the Ag/AgCl reference electrode changes linearly versus time in cyclical phases, while the current is detected between GC and platinum electrode (Pt). The detected current is plotted versus the applied voltage to obtain the typical cyclic voltammogram trace (Figure 1). The presence of substances that are oxidized/reduced will result in current between GC and Pt, which can be seen as characteristic peaks in the voltammogram at a defined potential. The oxidation or the reduction peak potential values are used to set the GC (integrated into the [[Q-Sensor]]) for a separate experiment to measure the [[Q redox state]] of a biological sample. The oxidation and reduction peak potentials can be influenced by 1) the respiration medium, 2) the type of [[Coenzyme Q | CoQ]], 3) the polarization window, 4) the scan speed, 5) the number of cycles, 6) the concentration of the analyte (CoQ), and 7) the initial polarization voltage. <be></br>:::-''See'': [[MiPNet24.12 NextGen-O2k: Q-Module]].</br>:::::[[MiPNet24.16 DatLab8.0: CV-Module]][[MiPNet24.16 DatLab8.0: CV-Module]])

Linked to DL-Protocols are templates for storing exported data in a database and for data analysis. Instrumental DL-Protocols are used for calibrations and instrumental quality control, without experimental sample in the incubation medium. DL-Protocols for [[substrate-uncoupler-inhibitor titration]] (SUIT) provide a guide through a sequence of [[coupling-control state]]s and [[Electron-transfer-pathway state]]s. A [[MitoPedia:_SUIT|library]] of evaluated and tested standard DL-Protocols is provided by the Oroboros team.

• Density  + ('''Density''', mass density ''ρ'' = ''m''· … '''Density''', mass density ''ρ'' = ''m''·''V''^-1 [kg·m^-3], is mass ''m'' divided by volume ''V''. Surface density ''ρ''_A = ''m''·''A''^-1 [kg·m^-2] ([[Bureau International des Poids et Mesures 2019 The International System of Units (SI) |SI]]). For a pure [[sample]] S, the mass density ''ρ''_S = ''m''_S·''V''_S^-1 [kg·m^-3] is the [[mass]] ''m'' of pure sample S per [[volume]] ''V''_S of the pure sample. With density ''ρ'' thus defined, the 'amount density' of substance B is ''ρ''_B = ''n''_B·''V''_B^-1 [mol·m^-3]. This is not a commonly used expression, but the inverse is defined as the [[molar volume]] of a pure substance ([[Cohen 2008 IUPAC Green Book |IUPAC]]), ''V''_m,B = ''V''_B·''n''_B^-1 [m³·mol^-1]. The pure sample is a pure gas, pure liquid or pure solid of a defined elementary entity. The amount [[concentration]], ''c''_B = ''n''_B·''V''^-1 [mol·m^-3] is the amount ''n''_B of substance B divided by the volume ''V'' of the mixture ([[Cohen 2008 IUPAC Green Book |IUPAC]]), and this is not called an 'amount density'. The term 'amount density' is reserved for an amount of substance per volume ''V''_S of the pure substance. This explicit distinction between 'density' related to the volume of the ''sample'' and 'concentration' related to the total volume of the ''mixture'' is very helpful to avoid confusion. Further clarification is required in cases, when the mass density ''ρ''_s of the sample in the mixture differs from the mass density ''ρ''_S of the pure sample before mixing. Think of a sample S of pure ethanol with a volume of 1 L at 25 °C, which is mixed with a volume of 1 L of pure water at 25 °C: after the temperature of the mixture has equilibrated to 25 °C, the total volume of the mixture is less than 2 L, such that the volume ''V''_S of 1 L pure ethanol has diminished to a smaller volume ''V''_s of ethanol in the mixture; the density of ethanol in the mixture is higher than the density of pure ethanol (this is incomplete [[additivity]]). The volume ''V''_s of sample s in a mixture is by definition smaller than the total volume ''V'' of the mixture. Sample volume ''V''_S and system volume ''V'' are identical, but this applies only to the case of a ''pure'' sample. ''Concentration'' is related to samples s per total volume ''V'' of the mixture, whereas ''density'' is related to samples S or s per volume ''V''_S = ''V'' or ''V''_s < ''V'', respectively ([[BEC 2020.1]]).)

The value of d''H'' in an open system, therefore, depends on the arbitrary choice of the reference state. In contrast, the terms in parentheses are the sum of all (total, t) partial energy transformations,</br> d_t''H'' = (d_e''Q'' + d_e''W'')</br>A partial enthalpy change of transformation, d_tr''H'', is distinguished from the total enthalpy change of all transformations, d_t''H'', and from the enthalpy change of the system, d''H''.

The distinction between exergonic and [[exothermic]] processes is at the heart of [[ergodynamics]], emphasising the concept of [[exergy]] changes, linked to the performance of [[work]], in contrast to [[enthalpy]] changes, linked to [[heat]] or thermal processes, the latter expression being terminologically linked to ''thermo''dynamics.inologically linked to ''thermo''dynamics.)
