AP Biology MCQ Practice Exam #1
Questions With Correct Answers
Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which
of the following best expalins how the properties of water contribute to this physiological
process? - answer✔✔The high heat of vaporization of water allows the body to remove excess
heat through a phase change of water from liquid to gas.
A student placed a semipermeable membrane inside a U-shaped channel with two chambers.
Membrane permits the movement of water but not salt. The student wants to vary the rate of
osmosis that occurs across the membrane. Which experimental design will result in the fastest
net rate of water movement into chamber A? - answer✔✔Placing salt in chamber A and distilled
water in chamber B.
What best describes the role of water in photosynthesis? - answer✔✔Water molecules donate
electrons to the electron transport chain.
What evolutionary advantage does compartmentalization of core metabolic processes offer
eukaryotes? - answer✔✔Evolution of a nucleus in eukaryotes separates the processes of
transcription and translation and they can be regulated separately.
Pyruvate dehydrogenase is an enzyme that converts pyruvate to acetyl-CoA. Acetyl-CoA is
further metabolized in the Krebs cycle. A researcher measured the accumulation of acetyl-CoA
in a reaction containing pyruvate and pyruvate dehydrogenase under several different conditions
5. Which of the following best describes the cellular location where pyruvate dehydrogenase is
most likely active?
6. The maximum production rate of acetyl-CoA under condition 1 is closer to which of the
following?
7. Which of the following observations provides the best evidence that acetyl-CoA negatively
regulates pyruvate dehydrogenase activity?
8. Which of the following best explains the buildup of lactic acid in individuals with the
mutation? - answer✔✔5. The mitochondrial matrix
6. 1 micromole/sec
Based on results, which best describes what protein X is? - answer✔✔Protein X is a transcription
factor.
Which of the following best explains the presence of prolactin in various vertebrate species? -
answer✔✔Prolactin is a homologous hormone because it has a common origin but different
functions in various species.
12. Which of the follwing best describes the production of DMSP by coral and coral symbionts?
13. Which of the following best describes the effect of temperature on corals' ability to produce
DMSP as shown in Figure 1?
14. Which of the following best describes the difference between the total amount of DSMP
produced by adults compared to juveniles at the start of the 32C trial.
15. In addition to the effect of temperature on DMSP produced by corals and theri symbionts,
whcih of the following relationships is also being considered in this experiment?
16. What best describes the scientists´ findings concerning the density of symbionts presented in
Figure 2?
17. What best explains the result of adult corals being exposed to elevated temperatures for
extended periods? - answer✔✔12. A negative feedback mechanisms that reverses the
environmental change.
13. Both juvenile and adult corals produce less DMSP at 27C than at 32C.
14. Adults corals produced 5 times more DMSP than juveniles produced.
15. Effect of additional DMSP produced by symbionts and the corals' age.
16. The symbiont density at 32C was different from the density at 27C on days 5 and 10 of the
experiment.
