Macromolecules

Question 1

Define macromolecules

Answer 1

Large, complex molecules that are composed of lots of monomers and bonded together to form polymers.

Question 2

Identify inorganic & organic compunds

Answer 2

Organic: Contain carbon& hydrogen atoms

Inorganic: Can have one or the other, but don’t contain both carbon and hydrogen atoms

Question 3

Difference/similarity between
monomers/polymers

Answer 3

Monomers: Small, single units that can join together to form larger molecules

Polymers: Large molecules made up of repeating monomer units

Question 4

Define and describe dehydration
synthesis/hydrolysis

Answer 4

Dehydration synthesis: It builds molecules up and require energy (removes water)

Hydrolysis: It breaks molecules down and release energy(adds a water molecule)

Question 5

Identify lipids,
carbohydrates,
proteins,
and nucleotides

Answer 5

1. Carbohydrates

-monosaccharides
-C,H,O

•provide quick energy
•provide structure to cells and organisms
•store energy

2. Lipids

-Fatty acids
-C,H,O

•store energy
•form major part of biological membranes
•stabilize animal membrane
•protection

3. Proteins

•carry out nearly all the functions of the cells

4. Nucleic Acids

-nucleotides
-C,H,O,N,P

•Genetic Information
