CARBOHYDRATES

Question 1

carbohydrates

Answer 1

contain h, o, c
in every carbon, there are 2H, and 1 O.
it is a source and store of energy,
it is a structure unit.

Question 2

monosaacharide

Answer 2

source of energy
soluble.

Question 3

disaacharide

Answer 3

soluble
maltose
sucrose-non reducing
lactose

Question 4

maltose

Answer 4

alpha+alpha

Question 5

surcose

Answer 5

alpha+furcose

Question 6

lactose

Answer 6

b glactose+alpha

Question 7

celobose

Answer 7

beta+beta

Question 8

how do these join

Answer 8

join by condensation reaction, which forms a glycosidic bonds

Question 9

glycodsic bonds

Answer 9

joins carbohydrates and forms glycosidic bond

Question 10

disaacharides broken to

Answer 10

monosaccharides, by a hydrolysis reaction.

Question 11

alpha glucose

Answer 11

energy source
component of starch, and glycogen

Question 12

beta glucose

Answer 12

energy source
component of celluose

Question 13

ribose

Answer 13

component of RNA, ATP and NAD.

Question 14

deoyribose

Answer 14

component of DNA

Question 15

polysaacharides

Answer 15

polymers of monosaccharides.
join a lot to form store of energy.
plants=starch
humans-glycogen

Question 16

glycogen

Answer 16

compact, so dosent take space.
branced-easily snipped by hydrolysis.
1-4 bonded chains, less tendency to coil.

Question 17

starch

Answer 17

amylose or amlypepticin

Question 18

amylose

Answer 18

compact
unbtranched
coils to spiral shape.
h2 bonding
hydroxyl groups insided making it less soluble.

Question 19

amylopepticin

Answer 19

1-6 glycosidic bonds.
also coils, h2 bonding
branches
not soluble

Question 20

celluose

Answer 20

found in plants (cell wall).
tough
insoluble
bonded thrugh condesation to make glycodsic bonds.
dosent spiral like alpha, straight lie by side.
h2 bonding make it stronger.

Question 21

why dosent celluose spira;

Answer 21

o, oh inverted in beta.

Question 22

microfibrils

Answer 22

lots of chains bounded

Question 23

bundle of microfibrils

Answer 23

cell wall

Question 24

structure and function of plant cell walls

Answer 24

micro/microfibrils have high tensile strength-prevents from bursting
macro-run in all directions.
space in macro to allow h20 and mineral ions to move. PERMEABLE
