**Question 13:** When electrons flow through the electron transport system from NADH to oxygen, what is the sequence of molecules through which they move?

In the electron transport chain, electrons typically move through a series of complexes and molecules in the following sequence: 

1. Complex I (NADH: ubiquinone oxidoreductase)
2. Ubiquinone (Coenzyme Q)
3. Complex III (cytochrome bc1 complex)
4. Cytochrome c
5. Complex IV (cytochrome c oxidase)

This process ultimately leads to the reduction of oxygen and contributes to the generation of ATP through oxidative phosphorylation.
