MitoEAGLE (2018) MitoEAGLE

Abstract: Note: Subscript ‘§’ indicates throughout the text those parts, where potential differences provide a mathematically correct but physicochemically incomplete description and should be replaced by stoichiometric potential differences (Gnaiger 1993b). A unified concept on vectorial motive transformations and scalar chemical reactions will be derived elsewhere (Gnaiger, in prep.). Appreciation of the fundamental distinction between differences of potential versus differences of stoichiometric potential may be considered a key to critically evaluate the arguments presented in Section 3 on the protonmotive force. Since this discussion appears to be presently beyond the scope of a MitoEAGLE position statement, Section 3 is removed from the next version and final manuscript. This section should become a topic of discussion within Working Group 1 of the MitoEAGLE consortium, following a primary peer-reviewed publication of the concept of stoichiometric potential differences.

Keywords: Mitochondrial respiratory control, coupling control, mitochondrial preparations, protonmotive force, chemiosmotic theory, oxidative phosphorylation, OXPHOS, efficiency, electron transfer, ET; proton leak, LEAK, residual oxygen consumption, ROX, State 2, State 3, State 4, normalization, flow, flux

COST Action MitoEAGLE
This manuscript on ‘Mitochondrial respiratory states and rates’ is a position statement in the frame of COST Action CA15203 MitoEAGLE. The list of coauthors evolved beyond phase 1 in the bottom-up spirit of COST.
The global MitoEAGLE network made it possible to collaborate with a large number of coauthors to reach consensus on the present manuscript. Nevertheless, we do not consider scientific progress to be supported by ‘declaration’ statements (other than on ethical or political issues). Our manuscript aims at providing arguments for further debate rather than pushing opinions. We hope to initiate a much broader process of discussion and want to raise the awareness on the importance of a consistent terminology for reporting of scientific data in the field of bioenergetics, mitochondrial physiology and pathology. Quality of research requires quality of communication. Some established researchers in the field may not want to re-consider the use of jargon which has become established despite deficiencies of accuracy and meaning. In the long run, superior standards will become accepted. We hope to contribute to this evolutionary process, with an emphasis on harmonization rather than standardization.
