Lecture 3a

Question 1

4 macromolecules in all organisms

Answer 1

1. Nucleic acids: DNA (& RNA)
2. Proteins: made up of amino acids
3. Carbohydrates: ex glucose
4. Lipids: fats, phospholipids, cholesterol

Question 2

Major atoms in organic macromolecules for each types ( Lipids, Carbohydrates, Proteins, Nucleic acids)

Answer 2

Lipids: mostly C, H (small amount of O)
Carbohydrates: C, H, O
Proteins: C, H, O, N (some S)
Nucleic acids: C, H, O, P, N

Question 3

Nutrients from food into cells of organism

Answer 3

Macromolecules (carbs, lipids, proteins, & nucleic acids) in the food you eat get digested into monomers
↓
Monomers taken into cells, which assemble the monomers into macromolecules, as needed by each cell

Question 4

Macromolecule structure

Answer 4

Most macromolecules are LARGE molecules made up of smaller units called monomers.
held together by bonds.

Question 5

Hydrolysis

Answer 5

a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant

Question 6

dehydration synthesis

Answer 6

the creation of larger molecules from smaller monomers where a water molecule is released
