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
What is the products of the light reactions of photosynthesis that are utilized in the Calvin cycle?
ATP and NADPH
Photosynthesis is not responsible for
Where does the Calvin cycle take place?
Stroma of the chloroplast
In any ecosystem, terrestrial or aquatic, what group(s) is (are) always necessary?
In autotrophic bacteria, where are the enzymes located that can carry on carbon fixation (reduction of carbon dioxide to carbohydrate)?
In the cytosol
When oxygen is released as a result of photosynthesis, it is a direct by-product of
Splitting water molecules.
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?
blue and violet
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?
blue and red
In the thylakoid membranes, what is the main role of the antenna pigment molecules?
harvest photons and transfer light energy to the reaction-center chlorophyll
Which event occurs in the light reactions of photosynthesis?
Light is absorbed and funneled to reaction-center chlorophyll a.
Describe the functioning of photosystem II?
The electron vacancies in P680+ are filled by electrons derived from water
What is the event that is directly associated with photosystem I?
receiving electrons from the thylakoid membrane electron transport chain
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
To test for the liberation of O2 in the light.
What are the products of linear photophosphorylation?
ATP and NADPH
