1.4 glycogen

Question 1

Where is glycogen found in

Answer 1

Animals and bacteria

Question 2

What is the difference between structure of starch and glycogen

Answer 2

Structure of starch and glycogen are similar except in glycogen smaller chains but are more branched

Question 3

Where is glycogen stored in

Answer 3

Glycogen is stored in muscles and the liver

Question 4

Why’s the mass of carbonhydrate relatively small

Answer 4

This is because fat is the main storage molecule in animals

Question 5

Why does the structure of glycogen suit it for storage

Answer 5

Insoluble
It’s compact meaning a lot can be stored in small place
More branched meaning enzymes can act on it faster therefore more rapidly broken down to form glucose monomers. Glucose monomers used in respiration

Question 6

Why does glycogen need to be more branched than starch

Answer 6

Glycogen needs to be more branched because as they are mainly found in animals they need to be broken down at a higher rate as animals use up more energy than plants which are not as branches.
