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
Which of the following are products of the light reactions of
photosynthesis that are utilized in the Calvin cycle?
Photosynthesis is not responsible for
Where does the Calvin cycle take place?
In any ecosystem, terrestrial or aquatic, what group(s) is (are)
In autotrophic bacteria, where are the enzymes located that can carry
on carbon fixation (reduction of carbon dioxide to carbohydrate)?
When oxygen is released as a result of photosynthesis, it is a direct
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?
Halobacterium has a photosynthetic membrane that is colored purple.
Its photosynthetic action spectrum is exactly complementary (opposite
to) the action spectrum for green plants. What wavelengths of light do
the Halobacterium photosynthetic pigments absorb?
In the thylakoid membranes, what is the main role of the antenna
Which of the events listed below occurs in the light reactions of
Which statement describes the functioning of photosystem II?
Which of the following are directly associated with photosystem I?
Some photosynthetic organisms contain chloroplasts that lack
photosystem II, yet are able to survive. The best way to detect the
lack of photosystem II in these organisms would be
What are the products of linear photophosphorylation?
As a research scientist, you measure the amount of ATP and NADPH
consumed by the Calvin cycle in 1 hour. You find 30,000 molecules of
ATP consumed, but only 20,000 molecules of NADPH. Where did the extra
ATP molecules come from?
Assume a thylakoid is somehow punctured so that the interior of the
thylakoid is no longer separated from the stroma. This damage will
have the most direct effect on which of the following processes?
What does the chemiosmotic process in chloroplasts involve?
Suppose the interior of the thylakoids of isolated chloroplasts were
made acidic and then transferred in the dark to a pH 8 solution. What
would be likely to happen?
In a plant cell, where are the ATP synthase complexes located?
In mitochondria, chemiosmosis translocates protons from the matrix
into the intermembrane space, whereas in chloroplasts, chemiosmosis
translocates protons from
Which of the following statements best describes the relationship
between photosynthesis and respiration?
Where are the molecules of the electron transport chain found in
In photosynthetic cells, synthesis of ATP by the chemiosmotic
mechanism occurs during
Reduction of oxygen to form water occurs during

The splitting of carbon dioxide to form oxygen gas and carbon
compounds occurs during
Generation of proton gradients across membranes occurs during
What is the relationship between wavelength of light and the quantity
of energy per photon?
P680⁺ is said to be the strongest biological oxidizing agent. Why?
Some photosynthetic bacteria (e.g., purple sulfur bacteria) have only
photosystem I, whereas others (e.g., cyanobacteria) have both
photosystem I and photosystem II. Which of the following might this
electron flow may be photoprotective (protective to light-induced
damage). Which of the following experiments could provide information
on this phenomenon?
Carotenoids are often found in foods that are considered to have
antioxidant properties in human nutrition. What related function do
they have in plants?
In thylakoids, protons travel through ATP synthase from the thylakoid
space to the stroma. Therefore, the catalytic "knobs" of ATP
synthase would be located
In metabolic processes of cell respiration and photosynthesis,
prosthetic groups such as heme and iron-sulfur complexes are
encountered in components of the electron transport chain. What do
In a cyanobacterium, the reactions that produce NADPH occur in
The reactions that produce molecular oxygen (O₂) take place in
The accumulation of free oxygen in Earth's atmosphere began
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.
Where do the enzymatic reactions of the Calvin cycle take place?
