Coupling-control state

Description

Coupling-control states are defined in mitochondrial preparations (isolated mitochondria, permeabilized cells, permeabilized tissues, homogenates) as LEAK, OXPHOS, and 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, ROUTINE, and ET states of respiration with corresponding rates L, R, E, using membrane-permeable inhibitors of the phosphorylation system (e.g. oligomycin) and uncouplers (e.g. CCCP). Coupling-control protocols induce these coupling control states sequentially at a constant electron-transfer-pathway state.
