ACCURATE ANSWERS AND EXPERT
REVIEW NOTES
●● How is photosynthesis similar in C4 plants and CAM plants?
Answer: both types of plants use PEP-carboxylase and Rubisco to "x
CO2
●● Which of the following sequences is the closest representation of the
flow of electrons during non-cyclic photosynthesis?
Answer: H2O --> photosynthetcic electron transfer chain --> NADPH
●● Theodor W. Engelmann illuminated a "lament of algae with light that
passed through a prism, thus exposing different segments of algal
filament to different wavelengths of light. He added aerobic bacteria and
then noted in areas in which the bacteria congregated. He noted that the
largest groups of aerobic bacteria were found in the areas illuminated by
the red and blue light. What might be the best conclusion Engelmann
could make about the congregation of bacteria in the red and blue areas?
Answer: bacteria congregated in these areas because these areas pduced
more oxygen via photosynthesis in the algae
●● Compared to C3 plants, C4 plants?
, Answer: C4's can continue to fix CO2 even at relatively low CO2
concentrations and high oxygen concentrations.
●● As a plant physiology researcher, you measure the amount of ATP
and NADPH consumed by the Calvin cycle in 1 hour in tobacco plants.
You observe 30,000 molecules of
ATP are consumed, but only 20,000 molecules of NADPH are
consumed. Which of the following processes is likely to have produced
the addiitonal 10,000 molecules of ATP
Answer: cyclic electron flow
●● A flask containing photosynthetic green algae and a control flask
containing water with no algae are both placed under a bank of lights,
which are set to cycle between 12
hours of light and 12 hours of dark. The dissolved oxygen
concentrations in both flasks are monitored. Predict what the relative
dissolved oxygen concentrations will be in
the flask with algae compared to the control flask.
Answer: the dissolved oxygen in the flask with algae will be higher in
the light, but lower in the dark
●● The drug cytochalasin B blocks the assembly of G-actin subunits.
Which of the following aspects of the cell cycle would most likely be
disrupted by cytochalasin B?
Answer: cleavage furrow formation and cytokinesis during cell division
