enzymes
One example is hydrolysis, where water is used to break the bonds between molecules. Another example is oxidation, where molecules lose electrons and break into smaller fragments. Both of these reactions result in the breakdown of larger molecules into smaller ones.
hydrolysis: hydro = water, lysis = cutting
No, a chemical reaction involving different molecules does not involve a direct exchange of atoms or positions between the molecules. Each molecule in a reaction follows its specific reaction pathway based on the reactivity and bonding preferences of the atoms within it.
That happens all the time. Smaller molecules combine to form larger molecules; larger molecules break up into smaller molecules.
Yes, a reactant is a substance that takes part in and undergoes change during a reaction. Products are those substances produced as a result of a reaction. Catalysts are substances that take part in a reaction but are left unchanged by the reaction (they speed up the reaction rate).
The reaction would be termed a chemical reaction.
The breakdown of water molecules into hydrogen and oxygen molecules is an example of a decomposition reaction. In this reaction, water is broken down into its constituent elements.
Amylase helps speed up breakdown of starch molecules.

A chemical reaction that breaks down molecules is called a decomposition reaction. In this type of reaction, a single compound is broken down into two or more simpler substances. An example is the breakdown of hydrogen peroxide into water and oxygen gas.

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.
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.

Catabolism
No
In a chemical reaction, atoms are rearranged, such that some atoms get out of some molecules and join other molecules.
