What is the correct order of electron flow in the electron transport chain?
NADH -> Complex I -> CoQ -> Complex III -> Cytochrome c -> Complex IV -> O2
FADH2 -> Complex II -> CoQ -> Complex III -> Cytochrome c -> Complex IV -> O2
Complex I -> NADH -> CoQ -> Complex III -> Cytochrome c -> Complex IV -> O2
O2 -> Complex IV -> Cytochrome c -> Complex III -> CoQ -> Complex I -> NADH

Explanation

The correct order is NADH -> Complex I -> CoQ -> Complex III -> Cytochrome c -> Complex IV -> O2 and FADH2 -> Complex II -> CoQ -> Complex III -> Cytochrome c -> Complex IV -> O2.
