The correct answer among all the other choice is A. Electron transport chain. This is the stage of cellular respiration that does not involve any carbon-based compounds as a reactant or product. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

Answer:

The correct answer would be A. Electron transport chain.

In cellular respiration, all the complexes associated with electron transport chain are usually located in the inner membrane of the mitochondria.

The electrons released by the oxidation of NADH and FADH₂ are transported by various electron carriers associated with electron transport chain. The electrons are finally accepted by oxygen to form water which is released as a byproduct.

The flow of electron through the electron transport chain is coupled with the pumping of protons across the membrane which leads to the formation of proton gradient.

This gradient (chemiosmosis) is used by ATP synthase located in the inner membrane to phosphorylate ADP into ATP.

No carbon based compound is used as reactant or product in electron transport chain.
