Macromolecules Part 1

Question 1

Polymers

Answer 1

They build from dehydration synthesis, which removes water to form linkages

Question 1

Macromolecules

Answer 1

Large molecules built from smaller molecules ( energy transfer

Question 2

Hydrolysis

Answer 2

The breakdown of polymers ( adds water breaking a bond )

Question 3

What are the tupes of Carbohydrates?

Answer 3

Monosaccharides- single
Disaccharides- two
Oligosaccharides- 3 or 5
Polysaccharides- A lot

Question 3

What are the four macromolecules

Answer 3

Carbohydrates ( energy and structure )
Lipids ( Long term energy storage and cell functioning )
Proteins ( Catalyst actions, they do everything )
Nucleic acids ( code for proteins, deliver genetic functions )

Question 4

What holds carbohydrates together?

Answer 4

glycosidic

Question 5

Glycogen

Answer 5

Angle of bonds result in coiling into helix ( a-1 4 linkages )

Question 6

Starch

Answer 6

A-glucose monomers ( a-1 4 linkages )

Question 7

Cellulose

Answer 7
