monomers and polymers

Question 1

describe the chemical reactions involved in the conversion of polymers to monomers and monomers to polymers.
give two named examples of polymers and their associated monomers to illustrate your answer. (5)

Answer 1

1. a condensation reaction joins monomers together and forms a chemical bond and releases water;
2. a hydrolysis reaction breaks a chemical bond between monomers and uses water;
3. e.g. amino acid and polypeptide, protein;
4. e.g. nucleotide and polypeptide, DNA or RNA;
5. peptide bond between amino acid;

Question 2

what is a monomer? (1)

Answer 2

is a smaller/repeating unit/molecule from which larger molecules/polymers are made;
