1.4 Starch, Glycogen And Cellulose Flashcards
1
Q
Starch’s structure related to its function
A
- insoluble-> doesn’t affect water potential
- helical -> compact
- large -> cannot diffuse out of cell
- branches chains -> easy to remove glucose
2
Q
Where is starch found?
A
Plants in the form of small grains
3
Q
Monosaccharide of starch
A
Alpha glucose
4
Q
Role of starch
A
Energy source
5
Q
What is the branched part of starch called?
A
Amylopectin
6
Q
What is the unbranched part of starch called?
A
Amylose
7
Q
What does starch consist of?
A
2 different carbohydrates amylose and amylopectin
8
Q
glycogen’s structure related to its function
A
- insoluble-> doesn’t affect water potential
- helical -> compact
- large -> cannot diffuse out of cell
- > more branched than starch-> easily remove glucose for respiration and movement
9
Q
where is glycogen found?
A
animals
10
Q
role of glycogen
A
energy source
11
Q
monosaccharide of starch
A
alpha glucose
12
Q
cellulose’s structure related to its function
A
- long straight chains
- become linked together by many hydrogen bonds
- form fibrils
- provide strength to cell wall
13
Q
where is cellulose found?
A
plants
14
Q
role of cellulose
A
provide support and rigidity
15
Q
