Due: September 30, 2010
All questions should be answered on a separate sheet of paper OR typed using complete
sentences.
1. Identify and describe the unifying themes of biology.
2. Name the 8 characteristics of all living things.
3. Describe a problem you are having and apply the steps of the scientific method of
problem solving.
4. Describe an atom in terms of particle charge, atomic number, atomic weight
and valence.
5. Describe the importance of molecular bonding and distinguish among strong
and weak bonds, giving biological examples of each. (polar covalent, nonpolar
covalent, ionic and hydrogen bonds)
6. Describe how the unique chemical and physical properties of water influence
life on earth.
7. Describe water’s dissociation and how that affects the pH of a given solution.
8. Distinguish between acidic and basic solutions and the role of buffers in
aqueous solutions.
9. Identify the 6 major elements found in living things.
10. Describe the role of carbon in molecular diversity, its characteristics, and its
forms of organization structures.
11. Distinguish among the three types of isomers: structural, geometric, and
enantiomers.
12. Recognize the major functional groups and describe the traits they give their
macromolecule.
13. Define monomer, polymer, hydrolysis, and dehydration synthesis and be able
to give specific examples from each of 4 macromolecule groups.
14. Describe the chemical properties, bond types, and biological importance of
macromolecules.
15. Recognize and give examples of four levels of protein conformation and relate
them to denaturation.
16. Distinguish between endergonic/exergonic reactions, anabolic/catabolic
pathways, kinetic/potential energy, and open/closed sytsems.
17. Describe the first and second laws of thermodynamics.
18. Describe an enzyme in terms of its function in chemical reactions and
substrate/product relationships.
19. Define and recognize examples of the following terms related to enzymes:
catalysts, active site, substrate, product, induced fit, competitive inhibition,
noncompetitive inhibition, activation energy, and feedback inhibition.
20. Identify the effect on initial reaction rates produced by changes in temperature,
pH enzyme concentration and substrate concentration.
