Answer 14

makes maltose + water (arranged side by side )
disaccharide

Question 15

what is hydrolysis

Answer 15

can break maltose easily into 2 glucose
splits disaccharide into the 2 monosaccharide

grains and some veg

Question 20

Glycogen uses and sources

Answer 20

Made in animals
extra glucose is converted into glycogen and stored in liver
can be converted back when blood sugar is low

Question 21

Cellulose sources and uses

Answer 21

found in plant cell walls
hard to digest but provides fibre for waste elimination

Question 22

Question 26

What is Unsaturated fat

Answer 26

not all carbon branches are filled with hydrogen, could have double bond
liquid at rm temp
oils, fish oil, veg oil

Question 27

What is the Phospholipid Bilayer

Answer 27

Cell membrane
Hydrophilic head (phosphate + nitrate + glycerol)
and hydrophobic tail (2 fatty acids)
