Bio 1500 - exam 3
1. memorize the 4 classes of organic molecules: carbohydrates, proteins, lipids, nucleic acids
2. what are the properties of carbohydrates?: hydrophilic, polar, water soluble; ratio of carbon to
hydrogen to oxygen of 1:2:1; classified as mono-, di-, or poly- saccharides
3. list familiar examples of carbohydrates: glucose, sucrose, lactose, fructose
4. what is the function of carbohydrates?: provide energy
5. what are the properties of lipids?: non polar, hydrophobic
6. list familiar examples of lipids: fats, oils, waxes, phospholipids, steroids
7. what is the function of lipids?: store energy
8. what are the properties of proteins?: made from amino acid polymers, diverse range of functions,
denaturation
9. list familiar examples of proteins: enzymes, hormones
1/6
, 10. what are the functions of proteins?: Transport substances, speed up reactions, structural support,
make hormones
11. what are properties of nucleic acids?: - polar
- hydrophilic
- DNA and RNA
12. list familiar examples of nucleic acids: DNA, RNA
13. what is the function of nucleic acids?: store and transmit genetic information
14. what are the building blocks of carbohydrates?: Monosaccharides or simple sugars
15. what are the building blocks of lipids?: fatty acids and glycerol
16. what are the building blocks of proteins?: amino acids
17. what are the building blocks of nucleic acids?: nucleotides
18. explain the relationship between the terms monomer and polymer: monomers
are single subunits (building blocks) of macromolecules. when monomers combine with each other using covalent
bonds, it forms larger molecules called polymers.
