Because electrons lose potential energy when they shift toward a more electronegative atom, these redox reactions releases energy

Mitochondrial Respiratory ETS - Summary

4 Complexes

I: Electrons passed from NADH to Coenzyme Q

II: Electrons passed from FADH2 to Coenzyme Q

III: Electrons passed from Q to Cytochrome c

IV: Electrons passed from Cytochrome c to O2

Alternative steps drive protons out of the matrix

Complex I

Electrons transfer from NADH to FMN, then to Fe-s and finally to Q

As electrons are transferred from NADH to ubiquinone (Q), Complex I transfers four protons from the matrix to the intermembrane space

The 4 H+ are relayed through hydrogen bonding network
