They are called enzymes. They aren't necessarily considered molecules, but I suppose they are, perhaps very large ones. These enzymes act as a catalyst to speed the decompositions along. Stomach acid helps by oxidising the food as well as creating the environment for the proteins to function.

The type of reaction responsible for the breakdown of large molecules into smaller ones is referred to as the catabolic reaction or catabolism.
First chemicals bonds in the starting substances must break. Molecules are always moving. If the molecules bump into each other with enough energy,the chemical bonds in the molecules break. ;)
Catalysts are chemicals that can speed up a reaction but don't actually get used up themselves. Catalysts that slow reactions down are called negative catalysts or inhibitors. Manganese dioxide is a catalyst that speeds up the breakdown of hydrogen peroxide into water and oxygen. When a catalyst acts in a living organism it is called an enzyme. Human saliva has the enzyme amylasewhich breaks down carbohydrates into glucose.
Decomposition is its own category of chemical reaction. A reaction in which different molecules trade positions is known as an exchange reaction, as pairs of molecules essentially exchange places with one another.

The reaction would be termed a chemical reaction.

The CFC molecules are man made chemicals for refrigeration. The molecules on reaction release 2 gases. These gases are Chlorine and Fluorine.
Amylase helps speed up breakdown of starch molecules.
Hydrolysis is the reaction that stems from the breakdown of large molecules by the enzymatic addition of water. Hydrolysis is step leading to the degradation of the substance. It is a chemical reaction in which a molecule of water is added to a substance. At times water and the substance will split and one part of the parent molecule will receive one hydrogen ion.

the potential energy of the molecules changes during a reaction.

A decomposition reaction does not involve molecules trading positions. When two different molecules or pairs of molecules change position with one another, the chemical reaction is known as an exchange reaction.
