Photosynthesis Flashcards
Where does the Calvin cycle occur in chloroplast
The stroma
where do light capturing reactions occur in the chloroplast
thylakoid membrane
how many turn of Calvin cycle required to produce one glucose molecule
6
primary function of the Calvin cycle
construct simple sugars from carbon dioxide
what process in plants produces the most ATP for cellular activities
cellular respiration
where does a plants biomass come from
air
after leaving photosystem II electrons loose energy, what happens to this energy
establishes and maintains protein gradient for the production of atp
what is the primary outcome of the activity of photosystem I
NADP+ is reduced
electron excited by absorption of light are transferred to plastoquinone via phephytin. where do replacement electrons come from
water
what is the source of atmospheric O2 released during photosynthesis
produced during the splitting of water molecules during light capturing reactions
Calvin cycle inputs
ATP, NADPH, CO2
where does the Calvin cycle occur
in the stroma
Suppose that the concentration of CO2 available for the Calvin cycle decreased by 50% (because the stomata closed to conserve water).
Which statement correctly describes how O2 production would be affected? (Assume that the light intensity does not change.)
. In the light reactions, light energy is used to oxidize Blank to Blank.
The electrons derived from this oxidation reaction in the Calvin cycle are used to reduce Blank to Blank.
The Calvin cycle oxidizes the light-reactions product to .
