The oxygen required for the 'aerobic' nature of the Krebs cycle is used directly in which step?
Show answer and explanation
Correct answer: None of these steps
Oxygen is not used directly in any step of the Krebs cycle. It is the final electron acceptor in the Electron Transport Chain; without it, the ETC stalls, leading to a shortage of NAD+ and FAD, which stops the Krebs cycle.
