In order to break down (or digest) a polymer, enzymes must add in water to break the bonds between the monomers. During this
process, a hydrogen (H) from the water molecule is added to one of
the monomers and a hydroxyl (OH) from the water molecule is added
to the other monomer, causing the bonds between the monomers to
break. What is this process called?
A. Condensation (Dehydration Synthesis)
B. Hydrolysis
C. Hydroxylation
D. Phosphorylation
