Q
Describe the chemical reactions involved in the conversion of polymers to monomers and monomers to polymers.
Give two named examples of monomers and their associated monomers to illustrate your answer. [5 marks]
A
A condensation reaction joins monomers and forms a bond and releases water
A hydrolysis reaction breaks a bond between monomers
A suitable example of polymers and the monomers from which they are made:
- amino acid and polypeptide/protein/enzyme/antibody
- nucleotide and polynucleotide/DNA/RNA
- alpha glucose and starch/glycogen
- beta glucose and cellulose
A second example
Reference to a correct bond within a named polymer
