Question 1

what is the equation for respiration

Answer 1

glucose + o2 = co2 + water

Question 2

what is the energy store in animals

Answer 2

Glycogen

Question 3

why is it beneficial that polysacharides are less soluble in water

Answer 3

if glucose molecules dissolved in the cytoplasm, it would reduce water potential and water would diffuse into the cell.

Question 4

Describe the structure of amylose

Answer 4

1,4 glycosidic bonds
long chain of alpha glucose
spiral shape
unbranches

Question 5

Describe the structure of amylopectin

Answer 5

Branched
1,4 glycosidic bonds and 1,6 glycosidic bonds
spiral shape held with hydrogen bonds.

Question 6

what is the function of amylopectin ang glycogen being branched

Answer 6

glucose can be snipped off by hydrolysis easily when required by respiratory substrates.
Compact

Question 7

why is glycogen more compact than amylopectin

Answer 7

because it has more branches

Question 8

describe the structure of glycogen

Answer 8

1,4 and 1,6 glycosidic bonds
compact
more branched than amylopectin
less spiralled than amylopectin

Question 9

what is the benefits of it being compact

Answer 9

takes up less space whilst providing more glucose units for respiratory substrate
