Answer 12

When water molecule is added to break the glycosidic bond

Question 13

What are polysaccharides?

Answer 13

Many monosaccharides bound together

Question 14

Property 1 in polysaccharides

Answer 14

They are inactive in both chemical and physical reactions

Question 15

Property 2 in polysaccharides

Answer 15

They are not very soluble in water therefore it wont affect the osmotic potential

Answer 17

Starch , Glycogen, and cellulose

Question 18

Property 1 of starch

Answer 18

It is insoluble

Question 19

Answer 20

Functional

Question 21

What is starch?

Answer 21

A polysaccharide made up of amylose and amylopectin

Question 22

Reason for the blue-black color change

Question 25

Property 4 of amylose

Answer 25

Soluble in water

Question 26

Property 1 of amylopectin

Answer 26

Branched

Question 27

Property 2 of amylopectin

Answer 27

Has a 1-4 and 1-6 glycosidic bond

Question 28

Property 3 of amylopectin

Answer 28

Insoluble in water

Question 29

Property 4 of amylopectin

Answer 29

Gives yellow-orange color

Question 30

What do amylose and amylopectin have in common?

Answer 30

Both are stored in the plant cell and they both are polymers of alpha glucose

Question 31

Is glycogen functional or structural?

Answer 31

Glycogen is functional

Question 32

What do amylopectin and glycogen have in common?

Answer 32

They both have the same glycosidic bond formation however glycogen is more branched

Question 33

Is cellulose functional or structural?

Answer 33

Cellulose is structural

Question 34

How is cellulose formed?

Answer 34

Cellulose is made up of beta glucose which is bonded by 1-4 glycosidic bonds which makes every other molecule inverted to form a straight chain that forms hydrogen bonds between the cellulose making cellulose microfibers which are then connected together and glued together by hemicellulose which then they form cellulose molecules/ fibers
