carbohydrates

Question 1

give two ways which the structures of starch is similar to cellulose

Answer 1

1. both are enpolysaccharides
2. monomers are linked by a glycocidic bond
3. contains glucose, carbon, hydrogen and oxygen

Question 2

the question about the milk, lactase and beads

Answer 2

1. it is a continuous reaction
2. beads can be reused
3. enzymes is more stable due to a controlled environment
4. no need to remove milk
5. avoid end -point inhibition

Question 3

explain difference in the structure of the starch molecules and the cellulose molecules show in in the diagram above

Answer 3

starch is a POLYMER of alpha glucose whilst cellulose is a polymer of beta glucose

also hydroxyl and hydrogen groups on carbon 1 are inverted

Question 4

explain hoe cellulose molecules are adopted for their function in plant cells

Answer 4

cellulose molecules are LONG and STRAIGHT CHAINS that are linked by HYDROGEN BONDS

these hydrogen bonds are grouped together to form fibrils

which provides strength rigidity to the cell wall
