Polymers

Question 1

What are polymers?

Answer 1

Polymers are long molecules formed when lots of small molecules called monomers join together. This reaction is called polymerisation.

Question 2

What are plastics made up of?

Answer 2

Polymers

Question 3

What is condensation polymerisation?

Answer 3

Condensation polymerisation involves monomers which contain different functional groups.

1) The monomers join together and form bonds between them, making polymer chains
2) For each new bond that forms, a small molecule (water) is lost
3) This is why it is called polymerisation condensation

Question 4

What two functional groups does an amino acid contain?

Answer 4

It contains a basic amino group and an acidic carboxyl group. An example of an amino acid is glycine.

Question 5

What are proteins?

Answer 5

Proteins are polymers of amino acids

Question 6

What are DNA molecules made of?

Answer 6

DNA molecules are made from Nucleotide polymers

Question 7

What are sugars?

Answer 7

Sugars are small molecules that contain carbon, oxygen, and hydrogen
