CAMPBELL BIOLOGY CHAPTER 10 QUESTIONS WITHACCURATE ANSWERS
E Accurate Answer - If photosynthesizing green algae are provided
with CO2 synthesized with heavy oxygen (18O), later analysis will show that
all but one of the following compounds produced by the algae contain the 18O
label. That one is A) PGA. B) PGAL. C) glucose. D) RuBP. E) O2
E Accurate Answer - Which of the following are products of the light
reactions of photosynthesis that are utilized in the Calvin cycle? A) CO2 and
glucose B) H2O and O2 C) ADP, Pi, and NADP+ D) electrons and H+ E) ATP and
NADPH
E Accurate Answer - What are the products of the light reactions that
are subsequently used by the Calvin cycle? A) oxygen and carbon dioxide B)
carbon dioxide and RuBP C) water and carbon D) electrons and photons E)
ATP and NADPH
A Accurate Answer - Where does the Calvin cycle take place? A) stroma
of the chloroplast B) thylakoid membrane C) cytoplasm surrounding the
chloroplast D) chlorophyll molecule E) outer membrane of the chloroplast
D Accurate Answer - In any ecosystem, terrestrial or aquatic, what
group(s) is (are) always necessary? A) autotrophs and heterotrophs B)
producers and primary consumers C) photosynthesizers D) autotrophs E)
green plants
E Accurate Answer - In autotrophic bacteria, where are the enzymes
located that can carry on organic synthesis? A) chloroplast membranes B)
nuclear membranes C) free in the cytosol D) along the outer edge of the
nucleoid E) along the inner surface of the plasma membrane
B Accurate Answer - When oxygen is released as a result of
photosynthesis, it is a by-product of which of the following? A) reducing
NADP+ B) splitting the water molecules C) chemiosmosis D) the electron
transfer system of photosystem I E) the electron transfer system of
photosystem II
, B Accurate Answer - A plant has a unique photosynthetic pigment. The
leaves of this plant appear to be reddish yellow. What wavelengths of visible
light are being absorbed by this pigment? A) red and yellow B) blue and violet
C) green and yellow D) blue, green, and red E) green, blue, and yellow
C Accurate Answer - Theodor W. Engelmann illuminated a filament of
algae with light that passed through a prism, thus exposing different segments
of algae to different wavelengths of light. He added aerobic bacteria and then
noted in which areas the bacteria congregated. He noted that the largest
groups were found in the areas illuminated by the red and blue light.
9) What did Engelmann conclude about the congregation of bacteria in the red
and blue areas? A) Bacteria released excess carbon dioxide in these areas. B)
Bacteria congregated in these areas due to an increase in the temperature of
the red and blue light. C) Bacteria congregated in these areas because these
areas had the most oxygen being released. D) Bacteria are attracted to red and
blue light and thus these wavelengths are more reactive than other
wavelengths. E) Bacteria congregated in these areas due to an increase in the
temperature caused by an increase in photosynthesis.
D Accurate Answer - An outcome of this experiment was to help
determine A) the relationship between heterotrophic and autotrophic
organisms. B) the relationship between wavelengths of light and the rate of
aerobic respiration. C) the relationship between wavelengths of light and the
amount of heat released. D) the relationship between wavelengths of light and
the oxygen released during photosynthesis. E) the relationship between the
concentration of carbon dioxide and the rate of photosynthesis.
B Accurate Answer - If you ran the same experiment without passing
light through a prism, what would you predict? A) There would be no
difference in results. B) The bacteria would be relatively evenly distributed
along the algal filaments. C) The number of bacteria present would decrease
due to an increase in the carbon dioxide concentration. D) The number of
bacteria present would increase due to an increase in the carbon dioxide
concentration. E) The number of bacteria would decrease due to a decrease in
the temperature of the water.
A Accurate Answer - What wavelength of light in the figure is
mosteffective in driving photosynthesis? A) 420 mm B) 475 mm C) 575 mm
D) 625 mm E) 730 mm
