AAMC Test 3 Questions and Answers
Question 1
3 equations for energy of capacitor
Correct Answer
1/2 C(V^2)
1/2 (Q^2)/C
1/2 QV
Question 2
What is the formula for changing Celcius to Kelvin?
Correct Answer
degrees in Celcius + 273= temperature in Kelvin
AAMC Practice Test 3: Chem/ Phys: Q 11
Question 3
which of the follow is least likely to occur in a muscle fiber that is metabolizing
anaerobically?
a) fermentation of glucose to lactic acid
b) phosphorylation of ADP within the electron transport chain
c) depletion of stores of glycogen
d) acidification of the cytoplasm
Correct Answer
B
the ETC only provides ATP when it is metabolizing aerobically

,Question 4
when you de-protonate a substrate are you adding or removing a H+
and what happens to the pH when you de-protonate the substrate?
Correct Answer
you are removing a H+
the pH increases (becomes more basic)
Question 5
#18. What is the period of the voltage source that operates the plasma pencil?
Correct Answer
1000ns
Because the period of a time-varying signal is the shortest repitition time. According
to fig 2, each pulse is on for 500ns, then off for 500ns. Thus the time between
consecutive pulse is 500ns + 500ns = 1000ns

,Question 6
convergent evolution
VS
divergent evolution
VS
parallel evolution
Correct Answer
Convergent: Different organisms/lineage, evolving closer together to be similar,
using different mechanisms. i.e. dolphin and the shark. They have analogous
structures
Divergent: Same lineage, evolving apart to be more different. i.e. bat and horse are
both mammals but different structures
Parallel: similar to convergent but begins with organisms that are related.
Question 7
DNA replication
Correct Answer
Question 8
A=B --> C+D Ksp =?
Correct Answer
Ksp = [A][B]

, Question 9
what happens to the substrate when the pH is greater than pI?
will it be negatively charged or positively charged?
will it bind to cathode or anode?
Correct Answer
it will be negatively charged
it will bind to anode
Question 10
what is a feature of cancerous cells, increased or decreased apoptosis?
Correct Answer
a feature of cancer cells is decreased apoptosis or the inhibition of apoptosis
because that will allow the cells to keep replicating and dividing even though they
should be killed off
Question 11
when you protonate a substrate are you adding or removing a H+
and what happens to the pH when you protonate the substrate
Correct Answer
you are adding a H+
the pH decreases (becomes more acidic)
