Does Krebs Cycle Require Oxygen?

The Krebs cycle does not need oxygen to function; nonetheless, oxygen is required for the last step of aerobic cellular respiration, oxidative phosphorylation. Previous reactions divided energy-rich organic molecules (carbohydrates, lipids, and proteins).

Similarly, Is the Krebs cycle aerobic or anaerobic?

Aerobic breathing

Also, it is asked, Why does the citric acid cycle stop without oxygen?

The electron transport chain is the sole element of aerobic respiration that consumes oxygen physically. The citric acid cycle, on the other hand, cannot take place in the absence of oxygen because there is no means to renew the NAD+ required for the process.
