Question 8

Benefit of coiled molecules -

Answer 8

compact, a lot of energy can be stored in a small space.

Question 9

Benefit of being insoluble -

Answer 9

does not diffuse out of the cell

no osmotic effect on the cell

Question 10

Benefit of being branched -

Answer 10

Can be broken down faster

Allows rapid release of glucose to provide energy in respiration.
