Answer 1

FADH2 is a reducing agent.

FAD is an oxidizing agent.

Step-by-step explanation:

The full form of FAD is flavin adenine dinucleotide. It is mainly a redox-active coenzyme which is associated with the different proteins and is involved with the enzymatic reactions in the metabolism.

FAD is obtained by donating or accepting electrons.

In the citric acid cycle,

succinate + FAD → fumarate +
`$FADH_2$`

Thus we see that FAD is an oxidizing agent while
`$FADH_2$` is a reducing agent.
