Carbohydrates

Question 1

Disaccharide

Answer 1

macromolecule consisting of 2 monosaccharides joined together by a glycosidic bond.

Question 2

Polysacharide

Answer 2

Molecule consisting of more than 2 sugar molecules joined together by glycosidic bonds.

Question 3

Glycosidic

Answer 3

Formed by condensation

Question 4

Glycosidic

Answer 4

separated by hydrolysis

Question 5

Starch

Answer 5

Mixture of amylose and amylopectin.

The main form of carbohydrate used for energy storage in plants.

Question 6

Amylose

Answer 6

Long, unbranching chains
1,4-glycosidic bonds
Chains coil into helical shape

Question 7

Amylopectin

Answer 7

Shorter chains than amylose
1,4-glycosidic bonds
Branches out (Carbon 1 bonds to Carbon 6)

Question 8

Glycogen

Answer 8

Main form of carbohydrate used for energy storage in animals.
Glycogen is stored in the muscles and in the liver.
In times of high energy usage, these organs hydrolyse the glycogen stored and break it down into glucose molecules which can be used in respiration.
