Monomers and Polymers Flashcards
1
Q
What is a monomer?
A
Smaller, repeating units that make up larger chains/polymers.
2
Q
What is a polymer?
A
A molecule made of many identical monomers.
3
Q
Give 3 examples of a monomer.
A
Nucleotide, amino acid and monosaccharide
3
Q
Give 3 examples of a polymer.
A
Polynucleotide/DNA, polysaccharide, polypeptide.
3
Q
What is a condensation reaction?
A
- A reaction that joins two molecules together
- By forming a chemical bond
- Whilst releasing a water molecule
4
Q
What is hydrolysis?
A
- A reaction that separates two molecules
- By breaking the bond between them
- Using a water molecule.
5
Q
Give an example of both a hydrolysis and condensation reaction.
A
- A condensation reaction between two amino acids forms a peptide bond between them whilst releasing a water molecule.
- Hydrolysis of two amino acids breaks the peptide bond between them whilst using a water molecule.
