Naturally occurring polymers

Question 1

What happens when glucose (monomers) molecules undergo condensation polymerisation

Answer 1

produce either soluble polymer (starch) or an insoluble polymer (cellulose) and water

Question 2

Why can’t humans break down cellulose

Answer 2

we do not produce the enzymes

Question 3

How is the structure of DNA formed

Answer 3

the 4 bases of the nucleotides (monomers ) form 2 polymer chains and the polymer chains cross link when bases link up causing giant molecules to twist into a double helix

Question 4

How do amino acids monomers form proteins

Answer 4

they join by condensation polymerisation to form a polypeptide and water, long chain polypeptides make a protein

Question 5

Amino acids contain 2 functional group

Answer 5

amino group (NH2) and carboxyl group (COOH) joined together by a peptide bond (C-N)

Question 6

What do the nucleotide monomers form

Answer 6

nucleotides/DNA

Question 7

What do the amino acid monomers form

Answer 7

polypeptides/proteins

Question 8

What do the glucose monomers form

Answer 8

starch or cellulose
