Respiratory electron transport system capacity of mitochondria in the experimentally controlled state of non-coupled respiration (fully uncoupled; state E), obtained in intact cells or mitochondrial preparations with defined substrates, by titration of an established uncoupler up to optimum concentration at maximum flux. Non-coupled respiration yields an estimate of ETS capacity. In this state E, the mt-membrane potential is collapsed, which provides a reference state for flux control ratios and for measurement of the mt-membrane potential.
