Where do the coenzymes NADH and FADH2 go after created in glycolysis, pyruvate oxidation and Krebs cycle? What happens to these coenzymes when they get there?

Question

What do you think ?

anonymous · Answer

I am really not sure @Abhisar

aaronq · Answer

They need to be "recycled", right? So if these are $\sf reduced$ when breaking glucose apart, what needs to happen for them to be used again?

abhisar · Answer

Yes, as @aaronq said. These NADH and FADH2 enters some cycle where these are recycled back into NAD and FAD. Now can you tell me the name of the cycle ?

anonymous · Answer

you are correct though @Shaekitchen , the Krebs cycle is your answer

abhisar · Answer

In presence of oxygen, NADH is recyled to NAD+ by Electron Transport chain. In the absence of oxygen it is recycled by an additional process called as Fermentation.
