• Exergonic  + ('''Exergonic''' transformations or process … '''Exergonic''' transformations or processes can spontaneously proceed in the forward direction, entailing the irreversible loss of the potential to performe [[work]] (''erg'') with the implication of a positive internal [[entropy production]]. [[Ergodynamic equilibrium]] is obtained when an exergonic (partial) process is compensated by a coupled [[endergonic]] (partial) process, such that the Gibbs energy change of the total transformation is zero. Final [[thermodynamic equilibrium]] is reached when all exergonic processes are exhausted and all [[force]]s are zero. The backward direction of an exergonic process is endergonic. 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.)

• Fatty acid oxidation  + ('''Fatty acid oxidation''' is a multi-step … '''Fatty acid oxidation''' is a multi-step process by which [[fatty acid]]s are broken down in [[β-oxidation]] to generate acetyl-CoA, NADH and FADH₂ for further electron transfer to CoQ. Whereas NADH is the substrate of CI, FADH₂ is the substrate of [[electron-transferring flavoprotein complex]] (CETF) which is localized on the matrix face of the mtIM, and supplies electrons from FADH₂ to CoQ. Before the ß-oxidation in the mitochondrial matrix, fatty acids (short-chain with 1-6, medium-chain with 7–12, long-chain with >12 carbon atoms) are activated by fatty acyl-CoA synthases (thiokinases) in the cytosol. For the mitochondrial transport of long-chain fatty acids the mtOM-enzyme [[carnitine palmitoyltransferase I]] (CPT-1; considered as a rate-limiting step in FAO) is required which generates an acyl-carnitine intermediate from acyl-CoA and carnitine. In the next step, an integral mtIM protein [[carnitine-acylcarnitine translocase]] (CACT) catalyzes the entrance of acyl-carnitines into the mitochondrial matrix in exchange for free carnitines. In the inner side of the mtIM, another enzyme [[carnitine palmitoyltransferase 2]] (CPT-2) converts the acyl-carnitines to carnitine and acyl-CoAs, which undergo ß-oxidation in the mitochondrial matrix. Short- and medium-chain fatty acids do not require the carnitine shuttle for mitochondrial transport. [[Octanoate]], but not [[palmitate]], (eight- and 16-carbon saturated fatty acids) may pass the mt-membranes, but both are frequently supplied to mt-preparations in the activated form of [[octanoylcarnitine]] or [[palmitoylcarnitine]].mitoylcarnitine]].)

FAO cannot proceed without a substrate combination of fatty acids & malate, and inhibition of CI blocks FAO.

FMN and FAD are the prosthetic groups of flavoproteins (flavin dehydrogenases). [[Electron-transfer-pathway state |Type F substrates]] (fatty acids) generate FADH₂, the substrate of [[electron transferring flavoprotein]] (CETF). Thus FADH₂ forms a junction or funnel of electron transfer to CETF, the [[F-junction]] (compare [[N-junction]], [[Q-junction]]), in the [[F-pathway control state]]. In contrast, FADH₂ is not the substrate but the internal product of [[succinate dehydrogenase]] (CII).
