Three major types of Chemical reactions

SYNTHESIS:

A chemical reaction in which larger, more complex atoms or molecules are formed from simpler ones.

DECOMPOSITION:

A chemical reaction in which a molecule is broken down into smaller molecules or it's constituent atoms.

EXCHANGE:

A chemical reaction in which binds are both made and broken; atoms become combined with different atoms.

Oxidation-reduction reactions is another group of important chemical reactions in living systems. Oxidation reduction reactions are decomposition reactions in that they are the basis of all reactions in which food fuels are catabolized for energy(that's, in which, ATP is produced). They are also a special type of exchange reaction because electrons are exchanged between the reactants. The reactant losing the electrons is referred to as the ELECTRON DONOR and is said to be oxidized; the reactant taking up the transferred electrons is called ELECTRON ACCEPTOR and is said to become reduced.
