Carbohydrates (CHO)

Question 1

Food examples

Answer 1

Yam
Bread
Banana 
Nuts
Vegetables

Question 2

Organic compounds 
( usually polymers (long chains) made up of many monomers)

Answer 2

• come from living things but there are many that will never be found in living organisms
• has atleast 1 carbon atom and can bind with a large number of other elements
• AKA macromolecules (very large )
• the ones that interest us are called BIOMOLECULES
• biomolecules are the carbohydrates, fats and oils(lipids), proteins and nucleic acids

Question 3

Types of sugars

Answer 3

Sucrose
Glucose
Fructose
Maltose

( simple carbohydrates)

Question 4

Types of starches

Answer 4

Potato 
Pasta
Wheat
Rice
Cellulose( found in cell walls)
Glycogen
Starch

(Complex carbohydrates)

Question 5

Formula for photosynthesis

Answer 5

6O2 + 6H20 ———>(sunlight and chlorophyll) C6H12O6 + 6O2

Question 6

Formula

What if the ration

Answer 6

C H O

Has a ratio of 2:1

Eg. C6H12O6 ( glucose )

Question 7

What are the different monosaccharides

Answer 7

Glucose
Fructose
Galactose

Question 8

What are the different disaccharides (2x monosaccharides)

Answer 8

Maltose = ( glucose + glucose)
Sucrose = ( glucose + fructose) ( in tea and coffee type sugar j
Lactose = ( glucose + galactose) ( milk sugar)

Question 9

Another name for Condensation reaction

Answer 9

Diyhydrationsynthesis

water is being lost and something is being built

Question 10

Disaccharide consists of

Answer 10

2x monosaccharides

Question 11

More than 2 monomers joint together

Answer 11

Polysaccharide

Eg. Starch = bland
Cellulose( make cell wall) = do not dissolve
Chitin( makes excess skeleton) ( found in mushrooms ) = no Crystals
Glycogen = glucose storage in animals

Question 12

Main function

Answer 12

Providing energy

Energy
Eg. Glucose —> instant energy OR
Glycogen (animals) and starch (plants) —> stored energy

Question 13

Very important part of nucleic acids

Answer 13

DNA - deoxyribose sugar ( oxygen missing)

C5H10O4

RNA - ribose sugar

C5H10C5

Question 14

Transport

Answer 14

Carbohydrates are transported through the blood as glucose

Starch and glycogen can’t be transported
