The addition of electrons to the compound is called as the reduction reaction. On the other hand, the removal of electrons is called as the oxidation.
The catabolism is a process by which electrons are removed from the compound. This is a oxidation reaction.The anabolism is a process by which electrons are added to the compound. This is the reduction reaction.
The anabolism is a process of formation of new complex substance from simple ones. This is a constructive process. The catabolism is a process of formation of simple substance from break down of complex ones. This is a destructive process.
