CP 1
How many stereoisomers of Compound 1 exist?
A.
8
B.
16
C.
32
D.
64 - Answer: Answer: 32
I multiplied wrong... bruh.
2^n where n is the number of chiral centers.
When will a precipitate be formed? - Answer: when the forward reaction is more favorable than
the reverse reaction.
,Kprecipitate > Ksp
CP 3
Why do kidney stones form in some individuals treated with Compound 1?
A.
[Ca2+] + [C2O42-] > Ksp
B.
[Ca2+][C2O42-] > Ksp
C.
[Ca2+] + [C2O42-] < Ksp
D.
[Ca2+][C2O42-] < Ksp - Answer: Answer: B
A precipitate is formed when the forward reaction is more favorable than the reverse reaction.
Kprecipitate > Ksp
CP 5
Which image best illustrates the electric field lines between the inside of an axon and the
surrounding extracellular solution? - Answer: Answer: B
I guessed on this question..
electric field lines represent movement of positive test charge. They should point away from
positive and point towards negative.
,Given in the passage: figure 2, where we see that there is a general negative charge occurring
within the neuron. Therefore
that inside of neuron has a negative voltage at baseline.
In this question, the axon interior will be the neuron = negative, therefore we will want to point
our electric field towards the negative axon interior, therefore B will be correct.
CP 7
Channel X transmits only the smallest substances dissolved in the extracellular fluid through the
axon membrane. Which substance does Channel X transmit?
A.
Proteins
B.
Sodium ions
C.
Potassium ions
D.
Chloride ions - Answer: Answer: B
because sodium is the smallest
refer to the periodic table.
CP 8
, What is the closest distance the electrodes used in an NCV test can be placed on a nerve in
order to measure the voltage change as a response to the stimulus?
A.
0.01 m
B.
0.1 m
C.
1.0 m
D.
10 m - Answer: Answer: B
Need to refer to figure 2... basically given in the graph we see that a signal lasts for less than 1
ms... therefore we see to multiply 1 ms x 100 m/s. = 1x10^-3 x 100 = 0.1
You will want to multiply by the constant speed because of the velocity formula.. then rearrange
to solve for distance... v = d/t... d = v * t...
d = (1x10-3) x (100) = 0.1
therefore 0.1 m is the correct answer.
CP 9
What information about an axon is required to calculate the current associated with an NCV
pulse?
A.
