Redox (Reduction-Oxidation) Reactions
These types of reactions are important in biology and occur very often in the cell. 
An oxidation reaction is always coupled with a reduction reaction.
Oxidation is the loss of electrons by an atom (said atom is oxidized); 
Reduction is the gaining of electrons by an atom (said atom is reduced).



Wize Concept
Oxidized atoms can be seen as either losing bonds with hydrogen atoms (e-) or gaining bonds to oxygen atoms; 
Reduced atoms can be seen as gaining bonds to hydrogen atoms or losing bonds to oxygen atoms.

Looking at the reaction below, what is true for the 4 numbered carbons?

A) Carbons 1 and 2 are reduced, whereas carbons 3 and 4 are oxidized 

B) Carbon 1 is oxidized, carbon 2 is reduced and carbons 3 and 4 are unchanged 

C) Carbon 1 and 2 are unchanged, and carbons 3 and 4 are reduced 

D) Carbon 1 is reduced, carbon 2 is reduced and carbons 3 and 4 are unchanged 

E) Carbons 1, 2, 3, and 4 are reduced
