Concept 1: Monomers and Polymers

Each cell assembles its own polymers by joining appropriate monomers together with the production of water.

Most biological molecules are very large and are built by assembling small molecules, or monomers, into long chains. The resulting molecules are called macromolecules, or polymers.

A process of linking monomers, called dehydration condensation, involves the removal of two hydrogen atoms and one oxygen atom to form water.

The animation illustrates the joining together of monomers by condensation (catalyzed by a polymerase enzyme) and the reverse process, in which added water results in hydrolysis (catalyzed by a hydrolase enzyme).
