BIOD 101 — 100 Questions with
Answers
Module 1: Chemistry of Life & Biomolecules
1. Q: What are the four major organic compounds that make up biomacromolecules?
A: Carbohydrates, nucleic acids, lipids, and proteins
2. Q: What is the atomic number of an atom with 6 protons, 6 neutrons, and 6
electrons?
A: 6
3. Q: Which subatomic particle carries a positive charge?
A: Proton
4. Q: What type of bond involves the sharing of electrons between atoms?
A: Covalent bond
5. Q: What type of bond involves the transfer of electrons from one atom to another?
A: Ionic bond
6. Q: Water is a polar molecule because:
A: The oxygen atom is more electronegative, creating partial charges
7. Q: What property of water allows it to resist temperature changes?
A: High specific heat
8. Q: What is the pH of a neutral solution?
A: 7
9. Q: A solution with a pH of 3 is considered:
A: Acidic
10. Q: What is the monomer of carbohydrates?
A: Monosaccharide
11. Q: Which of the following is a polysaccharide?
A: Starch
12. Q: What is the monomer of proteins?
A: Amino acid
13. Q: What is the monomer of nucleic acids?
A: Nucleotide
, 14. Q: Which is NOT a function of proteins?
A: Storing genetic information (that is the function of nucleic acids)
15. Q: Amino acids that must be obtained from the diet are known as:
A: Essential amino acids
16. Q: Why are lipids unique among biomacromolecules?
A: They are insoluble in water and are not made of monomers but from smaller
molecules chemically linked together
17. Q: What type of bond holds amino acids together in a protein?
A: Peptide bond
18. Q: What are the two major types of nucleic acids and their roles?
A: DNA stores genetic information; RNA deciphers genetic information to synthesize
proteins
19. Q: What is the primary function of carbohydrates?
A: Primary source of fuel/energy for organisms
20. Q: What elements make up carbohydrates?
A: Carbon, hydrogen, and oxygen
Module 2: Chemistry of Life & Taxonomy
21. Q: What are the characteristics of a living thing?
A: Order, evolutionary adaptation, regulation, energy processing, growth and
development, response to environment, reproduction
22. Q: What is the basic unit of life?
A: Cell
23. Q: What is metabolism?
A: The sum of all biochemical reactions
24. Q: What is a stimulus?
A: Anything that causes an organism to respond
25. Q: What is a behavioral adaptation? Give an example.
A: A change or process that allows an organism to become better suited for their
environment; e.g., a squirrel hibernating
26. Q: What are the three domains of life?
A: Archaea, Bacteria, Eukarya
