1.1 Biological Molecules

Question 1

Define monomer

Answer 1

Smaller units from which larger molecules are made
/Small basic molecular units that join together to firm polymers
E.g. glucose, amino acids

Question 2

Define polymer

Answer 2

Molecules made from a large number of monomers joined together
E.g. starch, protein

Question 3

Examples of monomers?

Answer 3

Amino acids
Nucleotides
Monosaccharides

Question 4

Describe how a condensation reaction joins two molecules together

Answer 4

Condensation reaction joins together with the formation of a chemical bond and involves the elimination of a water molecule

Question 5

Describe a hydrolysis reaction

Answer 5

A hydrolysis reaction breaks a chemical bond between two molecules and involves the use of a water molecule

Question 6

Monosaccharides?

Answer 6

Monosaccharides are the monomers from which larger carbohydrates are made

Question 7

Examples of monosaccharides?

Answer 7

Glucose, galactose, fructose

Question 8

What reaction and what bond forms when two monosaccharides join together?

Answer 8

A condensation between two monosaccharides forms a glycosidic bond
