Answer:

The reactant that is reduced is 
Explanation:
The complete equation is as below:

<em>Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.</em>
In the above reaction,
loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to
, hence the reducing agent.
<u>In order words, </u>
<u> is reduced while coenzyme Q is oxidized.</u>
