## Force or pressure? - The linear flux-pressure law

- "For many decades the pressure-force confusion has blinded the most brilliant minds, reinforcing the expectation that Ohm’s linear flux-force law should apply to the hydrogen ion circuit and protonmotive force. .. Physicochemical principles explain the highly non-linear flux-force relation in the dependence of LEAK respiration on the
*pmF*. The explanation is based on an extension of Fick’s law of diffusion and Einstein’s diffusion equation, representing protonmotive pressure ― isomorphic with mechanical pressure, hydrodynamic pressure, gas pressure, and osmotic pressure ― which collectively follow the generalized linear*flux-pressure law*." - Gnaiger E (2020) Mitochondrial pathways and respiratory control.

## Selected quotes

- p IX: .. the linear region is characterized by linear phenomenological laws and constant transport coefficients.
- p. 4: .. the pressure
*p*or the temperature*T*take well defined values at each point of the system and are therefore called intensive properties or variables. - p 15: However, even when a detailed theory will become available, thermodynamics of irreversible processes will still be of considerable importance, comparable to the importance of thermodynamics of equilibria, by showing which results depend on special microscopic assumptions, and which results are of general validity.
