6 ATP molecules is it possible to make for each pair of electrons passing to oxygen from one NADH reduced in the krebs cycle.
The maintenance of the proton gradient and the production of ATP by the ATP synthase are both accomplished krebs cycle by the flow of electrons via ETS. Six pairs of protons will be pumped out of the mitochondrial inner chamber when two pairs of electrons from NADH are transferred to oxygen. 6 ATP are created krebs cycle by the backflow of 6 pairs of protons.
