Carbohydrates

Question 1

A molecule

Answer 1

It is the smallest particle of a compound; it is formed from 2 or more atoms

Question 2

Anabolic reaction

Answer 2

Creates macromolecules from monomers (atoms or small molecules), so in any reaction substrates have to be less complex than products

Question 3

Condensation reaction

Answer 3

It is an anabolic reaction and it occurs when two smaller molecules combine to form a larger molecule, i.e glucose + glucose > maltose + water

Question 4

Catabolic reaction

Answer 4

Creates smaller molecules from macromolecules (products are less complex than the substrates

Question 5

Hydrolysis reaction

Answer 5

Hydrolysis is the splitting of a chemical body by addition of water, i.e. maltose + water > glucose + glucose

Question 6

Monosaccharides

Answer 6

Main function is storing energy - glucose, fructose, galactose all C6H12O6

Question 7

Disaccharides

Answer 7

Main function is transport, lactose, sucrose, maltose, all C12H22O11

Question 8

Polysaccharides

Answer 8

Main function is also storage, cellulose, glycogen, starch - all build from di or mono saccharides

Question 9

Types of lipids

Answer 9

Triglycerides and phospholipids

Question 10

Triglycerides

Answer 10

Are used for long term energy storage. They are made of a glycerol backbone with tree fatty acid chains attached

Question 11

Phospholipids

Answer 11

Make up the cell membrane

Question 12

what are carbohydrates?

Answer 12

organic compounds such as sugar or starch, and they are used to store energy

Question 13

function of lipids

Answer 13

They help with moving and storing energy, absorbing vitamins and making hormones.
