2 Lesson: BIO.A.2.2 Polymerization

Polymerization

Monomer is a molecule that has the ability to chemically bond with other molecules in a long chain.

Monomer is the building blocks of polymers.

Polymers are complex types of molecules

Breaking Bonds

• Catabolic process (Cat destroys with water)

• Depolymerization (Converting a polymer into a monomer)

• Hydrolysis (add water to break a bond)

Forming Bonds

• Anabolic process (Ana the builder)

• Polymerization (monomers connect to make polymers)

• Condensation Reaction

• Dehydration Synthesis (Removing water to made a bond)
