NS e-input


NS e-input or the NS-pathway control state is electron input from a combination of substrates for the N-pathway control state and S-pathway control state through Complexes CI and CII simultaneously into the Q-junction. NS e-input corresponds to TCA cycle function in vivo, with convergent electron flow through the ET-pathway. In mt-preparations, NS e-input requires addition not only of NADH- (N-) linked substrates (pyruvate&malate or glutamate&malate), but of succinate (S) simultaneously, since metabolite depletion in the absence of succinate prevents a significant stimulation of S-linked respiration. For more details, see: Additive effect of convergent electron flow.
