Question 1
What quantity of Compound 1 must be provided to prepare 100.00 mL of solution with a
concentration equal to Ki?
A.
48.4 mg
B.
24.2 mg
C.
5.64 mg
D.
2.92 mg
CORRECT ANSWER
Answer: D
Dimensional Analysis conversion
Question 2
If only [I] is increased, then [ESI] or [EI] increases. This is an example of:
A.
the Bose-Einstein Principle.
B.
the Heisenberg Uncertainty Principle.
1
,C.
the Le Châtelier's Principle.
D.
the Pauli Exclusion Principle.
CORRECT ANSWER
Answer: C
A: A collection of atoms close to absolute zero will coalesce into a single quantum state.
B: Possible density for electrons. Not much context for this problem.
C: In this question, [I] <--> [ESI] <--> [EI]. Increasing [I] will shift the equilibrium to the
right and produce an increased concentration of [ESI] or [EI].
D: 2 electrons in each spin. Not much context for this problem.
Question 3
Which structural change to Compound 1 would make it more water soluble?
A.
Replacing benzene CH with N in the ring
B.
Replacing C=O with C=CH2
C.
Replacing N-N=N with CH-CH=CH
D.
Replacing NH with NCH3
CORRECT ANSWER
Answer: A
2
, Like dissolves like, water is a polar compound, so making Compound 1 more polar will
allow it to be more soluble in water.
A: more polar
B: more non-polar
C: More non- polar
D: more non-polar
Question 4
In μM•s-1 and μM, what should the approximate values of kcat/KM and Ki be,
respectively, when [I] = 180 μM?
A.
33.5 and 15.7
B.
75 and 30.1
C.
150 and 60.3
D.
300 and 120.6
CORRECT ANSWER
Answer: C
Based upon Table 1, for any [I] value, Ki is 60.3, and Km is within the range of .14-
.15mM^-1 s^-1
Question 5
What functional group transformation occurs in the product of the reaction catalyzed by
Na+-NQR?
3
, A.
RC(=O)R → RCH(OH)R
B.
ROPO32- → ROH + Pi
C.
RC(=O)NHR'→ RCOOH + R'NH2
D.
RC(=O)OR'→ RCOOH + R'OH
CORRECT ANSWER
Answer: A
The passage states Na+-NQR is an enzyme which catalyzes the reaction oxidoreductase of
ubiquinone. Ubiquinone contains a ketone group and when reduced, contains an alcohol
group.
A: Ketone --> alcohol
B: Decomp reaction (not relevant)
C. Ketone --> carboxylic acid
D. Ketone --> carboxylic acid and alcohol
Question 6
What is the chemical structure of a component found in four of the five cofactors used by
Na+-NQR?
CORRECT ANSWER
Answer: B
The passage states the structure component found in 4 of the 5 cofactors used by Na+-
NQR is flavin. The structure of flavin is the following.
