MitoPathway control state: F
Respiratory stimulation of the FAO-pathway, F, by fatty acid FA in the presence of malate M. Malate is a type N substrate (N), required for the F-pathway. In the presence of anaplerotic pathways (e.g., mitochondrial malic enzyme, mtME) the F-pathway capacity is overestimated, if there is an added contribution of NADH-linked respiration, F(N) (see SUIT-002). The FA concentration has to be optimized to saturate the FAO-pathway, without inhibiting or uncoupling respiration. Low concentration of malate, typically 0.1 mM, does not saturate the N-pathway; but saturates the F-pathway. High concentration of malate, typically 2 mM, saturates the N-pathway.
