Which of the following statements regarding redox reactions is true? which of the following statements regarding redox reactions is true? redox reactions are only seen in the electron transport chain. redox reactions involve an oxidation reaction coupled with a reduction reaction. no metabolic reactions are redox reactions. redox reactions must either be oxidizing reactions or reducing reactions.

Redox reactions involve an oxidation reaction coupled with a reduction reaction.

Explanation:

A redox reaction is called like that because it involves a substance that is reducing and a substance that is oxidating, so it is Re-dox, this means that all of the chemicals reactions that involve a substance that looses an electron, are redox reactions, they are present in almost all of chemistry, from syntetic to biological chemistry, so the only correct option would be:

Redox reactions involve an oxidation reaction coupled with a reduction reaction.
