What are the names of reactions that build monomers into polymers and break down polymers into monomers?


Expert Answer

Step 1

The monomers are the molecules that combine with each other to form the polymers. Due to this, monomers are also classified as the smallest unit of the macromolecules. Amino acids, nucleotides, fatty acids, glycerol, and monosaccharides are examples of monomers.

The polymers are the macromolecules that are formed by combining a large number of monomer units. Proteins, DNA, RNA, fats, and polysaccharides are examples of polymers.

Step 2

When two monomer units combine to form a polymer, then water molecule is lost during this reaction, resulting in formation of a covalent bond between two monomers. Such reaction is termed as condensation reaction or dehydration reaction. Hence, the reaction that converts monomers into polymers is condensation reaction.

Step 3

Polymers are converted into their monomer units by the process of hydrolysis, which means to split water. During the process of hydrolysis, a water molecule is added to the polymer, resulting in th...
