True or false: ions may form by transferring an atomic nucleus (with or without electrons) to another molecule.

In order to break down a polymer, enzymes must add water to break the bonds between the monomers. During this process, a hydrogen from the wter is added to one of the monomers and a hydroxyl from the water molecule is added to th eother monomer,
