Fermentation is not considered as an oxydation reaction. ------------------------------------------------------------------ It may not usually be considered as such, but the oxidation state of C in sugar is zero, and the oxidation state of C in ethanol is -2. Any change in oxidation state can be treated as a redox process. Loss of electrons (or an increase of oxidation state) is oxidation, gain of electrons (or a decrease of oxidation state) is reduction. The carbon that ends up in the ethanol has decreased its oxidation state from 0 to -2 so those atoms have undergone reduction. Reduction cannot exist without a subsequent oxidation, so something else has undergone oxidation. The fermentation process also makes carbon dioxide. The C in those molecules has an oxidation state of +4, so those atoms of carbon have been oxidized. So the answer is --- both.

NADH (or FADH2) donates its electrons to a molecule producedby the same metabolic pathway that produced the electrons carried by NADH (or FADH2).
No. Making mixtures are physical changes and the chemical substances will not change.
The torn sheet has undergone a physical change, the burned sheet has undergone a chemical change, and the crumpled sheet has undergone a physical change.
A solution contains a solvent and one or more solutes. It is classified as a mixture because when a substance is dissolved in another substance, the two substances are still the same substances, not having undergone any significant chemical change, they are just mixed together.
