Short-Answer Questions

34)       What are some of the medical implications of the human genome project?

Ans:     The obvious use is in diagnosing disease and in developing methods to treat and cure diseases. Physicians will be able to account for individual genetic differences in determining the best medical treatment. Other answers may be correct.

Section:  Introduction

35)       What is the significance of hydrogen bonding in biochemical structures such as DNA?

Ans:     The bonds are weak enough to be easily disrupted; yet when many are present, they provide the stabilization necessary for larger structures such as DNA.

Section:  1.2

36)       Describe resonance structures.

Ans:     Resonance structures are ways of writing covalent bonds in which two or more alternate bonding patterns can be achieved. This is due to the sharing of electrons over several atoms. Common examples are found in peptide bonds, and in some of the DNA/RNA bases. Adenine is shown in the text.

Section:  1.3

37)       What is significant about the fact that metabolic processes are common to many organisms?

Ans:     These metabolic processes are extremely old, geologically, originating in a common ancestor.

Section:  1.1

38)       How is water able to be a solvent for so many biological molecules?

Ans:     Many biological molecules have polar characteristics. Water is extremely polar and is capable of competing with other polar molecules by weakening their electrostatic and hydrogen bonds. The oxygen atom can act as a hydrogen-bond acceptor, and the hydrogen can act as a donor.

Section:  1.3

39)       What is the net effect of many van der Waals interactions?

Ans:     At the interface of two large molecules, the numerous van der Waals interactions can substantially affect and stabilize the interaction.

Section:  1.3

40)       If most proteins are found surrounded by water in the cell, what type of functional groups would you expect to find on the surface of a water-soluble protein?

Ans:     Polar and charged amino-acid residues would be present on the surface of the protein.

Section:  1.3

41)       How are electrostatic forces used in protein folding?

Ans:     The attraction of two oppositely charged functional groups would be one of the forces helping to form the three-dimensional shape of the protein.

Section:  1.3

42)       If the First Law of Thermodynamics is true, how can biological processes be carried out?

Ans:     Although energy cannot be created or destroyed, it can take on different forms, such as heat or chemical energy. Thus, the energy can be stored as chemical bond energy, which can be used to do work.

Section:  1.3

43)       How can a cell exist if the Second Law of Thermodynamics is true?

Ans:     Entropy in a local area can be decreased, but only at the expense of increased entropy in the larger area, or universe.

Section:  1.3

44)       Provide a simple example of a process in which the entropy of a system changes.

Ans:     Several examples can be provided, including the random mixture of atoms when two different gases are mixed, or the creation of water molecules from energy gained following the mixture of oxygen and hydrogen under certain conditions.

Section:  1.3

45)       When solutions containing complementary single strands of DNA are mixed, a loss of entropy occurs. How is it that the Second Law of Thermodynamics is not violated?

Ans:     Heat must be released to the surroundings.

Section:  1.3

46)       What is the significance of using DG in biochemistry?

Ans:     Gibbs free energy, also called the free-energy change, is used to describe the energetics of a reaction. This symbol is used to determine if particular reactions will be spontaneous or biologically feasible.

Section:  1.3

47)       What thermodynamic and free-energy changes participate in protein folding?

Ans:     A combination of hydrogen bonds and van der Waals forces affect enthalpy and the entropy associated with hydrophobic interactions.

Section:  1.3

48)       How do hydrophobic interactions aid in protein folding?

Ans:     Hydrophobic interactions cause some nonpolar amino acids to aggregate and form the interior of the protein. This results in a net release of heat and a favorable change in the system enthalpy.

Section:  1.4

49)       What are the enthalpy and entropy changes that accompany the formation of DNA double helices from complementary single strands of DNA?

Ans:     There is a loss of entropy from the system because there are fewer degrees of freedom in the double helix as compared to the single strands.  Therefore, heat must be released when the two strands combine to form the double helix so as not to violate the Second Law of Thermodynamics.

Section: 1.3

50)       Describe the shape of methane.

Ans:     Methane is tetrahedral, with bond angles of about 109°.

Section:  Appendix
