adell [148]

Answer:

FADH2 is a reducing agent.

FAD is an oxidizing agent.

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.

Use the periodic table to answer the questions below.
Vera_Pavlovna [14]
The three of them have the same amount of electrons, so we can’t determine the right one on that ground. As you might know, Pauli said that electrons are always in the position of the lowest energy. So the first situation is impossible because there is a free place available that takes less energy. Then the 3rd situation is nor possible because if one electron has a different spin than the others, there is a magnetic obstruction that be prevented if the spin changes. This means that the second situation is the right one.
