3.1.1-Monomers and polymers

Question 1

What is a monomer?

Answer 1

Smaller units from which larger molecules are made

Question 2

What is a polymer?

Answer 2

Molecules made from a large number of monomers joined together

Question 3

What does a condensation reaction do?

Answer 3

Joins two molecules together with the formation of a chemical bond and involves elimination of a water molecule

Question 4

what does a hydrolysis reaction do?

Answer 4

breaks a chemical bond between two molecules involving the addition of a water molecule

Question 5

What is glucose molecular formula?

Answer 5

C6H12O6

Question 6

What does glucose exist as?

Answer 6

Two isomers-Alpha and Beta (same molecular formular different structure)

Question 7

How is the structure of alpha glucose different to beta glucose?

Answer 7

On Carbon 1 Alpha glucose has Hydrogen on top and hydroxyl on the bottom, beta swaps them around

Question 8

What is the general name for the monomers in a protein?

Answer 8

Amino acids

Question 9

Whats the general name for the monomers in a nucleic acid?

Answer 9

Nucleotides

Question 10

Describe the chemical reactions involved in the conversion of polymers to monomers and monomers to polymers.
Give 2 named examples of polymers and their monomers to illustrate your answer

Answer 10

Monomers to polymers-condensation reaction joins monomers together and forms a chemical bond and releases water
Polymers to monomers-a hydrolysis reaction breaks a chemical bond between monomer and involves the addition of a water molecule
Example-Protein and amino acid and Cellulose and beta glucose
