Biological Molecules: Monomers and Polymers Flashcards
1
Q
Define monomers:
A
Smaller units from which larger molecules are made.
2
Q
Define polymers:
A
Molecules made from a large number of monomers joined together.
3
Q
Give three examples of a monomer:
A
- Monosaccharides
- Amino acids
- Nucleotides
4
Q
Give three examples of a polymer:
A
- Polysaccharides
- Protein
- DNA
5
Q
Give the molecular structure of glucose:
A
C6 H12 O6
6
Q
What happens in a hydrolysis reaction?
A
Polymers break down to make monomers, a water molecule is gained.
7
Q
What happens in a condensation reaction?
A
Monomers join together to form a polymer, a water molecule is lost.
8
Q
What is a covalent bond?
A
A strong chemical bond where two atoms share a pair of electrons.
9
Q
What is an ionic bond?
A
A moderate chemical bond formed by the attraction between two oppositely-charged ions.
