monomers and polymers

Question 1

describe the chemical reactions of polymers into monomers and monomers into polymers
Give 2 named examples of polymers and their monomers (5)

Answer 1

1. condensation reaction joins monomers together and forms a chemical bond and releases water
2. Hydrolysis reaction breaks chemical bonds between monomers using water
3. for example, amino acid and polypeptide,
4. a-glucose and starch
5. amino acids joined by peptide bonds, a-glucose joined by glycosidic bonds

Question 2

define a monomer (1)

Answer 2

a smaller unit from which larger molecules are made

Question 3

define a polymer (1)

Answer 3

a larger molecule made from smaller repeating monomer units

Question 4

what are the monomers of and the bonds between them:
- DNA/RNA
- Cellulose
- Starch/Glycogen
- Polypeptide

Answer 4

-nucleotides- phosphodiester

-B-glucose- glycosidic

-a-glucose- glycosidic

-amino acids - peptide
