Biological Molecules

Question 1

Polymer

Answer 1

A long chain made of monomers e.g starch is made up of glucose units

Question 2

Monomer

Answer 2

Simple unit made of sugar e.g glucose, which can join together to form a polymer, e.g starch

Question 3

Dimer

Answer 3

Sugar made up of two units, e.g glucose + glucose

Question 4

Glucose

Answer 4

Most simple sugar, monosaccharide.
Glucose + glucose - disaccharide
Glucose x lots = polysaccharide

Question 5

Amino acid

Answer 5

Monomers which make up protein.
20 different types.
Essential amino acids need to be consumed.

Question 6

Polypeptide

Answer 6

Chain of amino acids (coils up to form protein)

Question 7

Glycerol

Answer 7

Component of lipids joined together with fatty acids

Question 8

Glycogen

Answer 8

Complex carbohydrates, glucose molecules joined together to form a long branched molecule called GLYCOGEN

Question 9

Starch

Answer 9

Complex carbohydrate, glucose molecules join to form a long straight molecule

Question 10

Lipids

Answer 10

One of the 7 food groups
Solid – fats
Liquid – oils

Question 11

Saturated fat

Answer 11

Found in animals, can block arteries in the heart

Question 12

Unsaturated fats

Answer 12

Found in plant oils, good for removing saturated fats from arteries (Benecol, Flora Proactive)
