5. When two atoms differing in electronegativity are joined in a covalent bond, then the:
a. electrons are shared equally between the atoms.
b. bond is nonpolar.
c. resulting compound is devoid of any dipole moment.
d. atom with the greater electronegativity attracts the bonded electrons more strongly.

Ans: d
Question Type: Multiple Choice

Blooms: Understanding
Difficulty: Moderate

6. The interactions between two proteins such as an antibody and an antigen or a hormone and its receptor are quite strong
despite the fact that these interactions consist of relatively weak noncovalent bonds. How can this be?

Ans: Two proteins can bind tightly because of molecular complementarity, in which multiple noncovalent bonds participate.
Although each individual bond is weak, the cumulative effect of many noncovalent bonds is a relatively strong and highly
specific interaction.

7. What produces the dipole of a water molecule?

Ans: The dipole of a water molecule is caused by the difference in electronegativity between O and H. The oxygen atom has
a greater electronegativity than the hydrogen atom. As a result, oxygen attracts the electrons in the O–H bond more strongly,
and the oxygen side of the bond has a slight net negative charge. This results in a dipole moment.

13. You discover that you suffer from a deficiency in the amino acid tryptophan. At the pharmacy, you find both D-
tryptophan and L-tryptophan supplements. Which do you purchase? Why?

Ans: You should choose L-tryptophan. All amino acids can exist as one of two stereoisomers ( D or L) because of asymmetry
around the α carbon. Proteins consist of the L form of amino acids, and as these stereoisomers possess distinct biological
properties and are not readily interconverted, you should choose the form that is normally utilized by cells.
