Answer:

[tex]FADH_2 + Q --> FAD + QH_2[/tex]

The reactant that is reduced is [tex]FADH_2[/tex]

Explanation:

The complete equation is as below:

[tex]FADH_2 + Q --> FAD + QH_2[/tex]

Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.

In the above reaction, [tex]FADH_2[/tex] loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to [tex]QH_2[/tex] , hence the reducing agent.

In order words, [tex]FADH_2[/tex] is reduced while coenzyme Q is oxidized.
