Understanding Polymers

Mr. Anderson explains polymers, large molecules made of monomers, using examples like cellulose, proteins, and DNA. He describes how polymers are built through condensation reactions and broken down by hydrolysis. The video includes a practical question about hydrolysis and concludes with the importance of polymers in digestion and nutrition.

What are the building blocks of polymers?

• Cells

• Proteins

• Monomers

• Atoms

Which of the following is a polysaccharide made of sugar?

What is the process called when water is removed to form a bond between monomers?

• Reduction

• Oxidation

• Condensation

• Hydrolysis

What is the opposite process of condensation, involving the addition of water?

• Synthesis

What happens to polymers during digestion?

• They are formed

• They are broken down into monomers

• They remain unchanged

• They are converted into lipids

Why are polymers important in biology?

• They are only found in plants

• They are waste products

• They are the building blocks of life

• They provide energy
