Description
CI+II e-input is electron input though Complexes CI plus CII simultaneously into the Q-junction corresponding to TCA cycle function in vivo, with convergent electron flow through the ETS. In mt-preparations, CI+II e-input requires addition not only of CI substrate (pyruvate+malate or glutamate+malate), but of succinate simultaneously, since metabolite depletion in the absence of succinate prevents a significant stimulation of CII.
