The electrons derived from this oxidation reaction in the light reactions are used to reduce ____ to _____.
NADP+ and NADPH
The electrons derived from this oxidation reaction in the Calvin cycle are used to reduce ______ to ______..
CO2 to G3P.
What occurs solely in Photosystem II only?
Reduction of electron transport chain between the two photosystems and the oxidation of water.
What occurs only in Photosystem I only?
Oxidation of electron transport chain between the two photosystems and the reduction of NADP+
What occurs in both Photosystems II and I.
Light absorption and the reduction of primary electron acceptor.
In the Calvin cycle, how many ATP molecules are required to regenerate RuBP from five G3P molecules?
Which term describes ATP production resulting from the capture of light energy by chlorophyll?
True or false? The chemiosmotic hypothesis states that the synthesis of ATP generates a proton gradient that leads to electron flow through an electron transport chain.
According to the chemiosmotic hypothesis, what provides the energy that directly drives ATP synthesis?
True or false? The region of ATP synthase that catalyzes the production of ATP from ADP and inorganic phosphate spans the chloroplast membrane.
What is the biological significance of the light-independent reactions of photosynthesis?
They convert carbon dioxide to sugar.
Which of the following reactions ensures that the Calvin cycle can make a continuous supply of glucose?
Regeneration of RuBP
C4 plants differ from C3 and CAM plants in that C4 plants _____.
Transfer fixed carbon dioxide to cells in which the Calvin cycle occurs.
Which of the following sequences correctly represents the flow of electrons during photosynthesis?
H2O---->NADPH----> Calvin cycle
How is photosynthesis similar in C4 plants and CAM plants?
In both cases, rubisco is not used to fix carbon initially.
Which of the following statements is a correct distinction between autotrophs and heterotrophs?
Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
In mechanism, photophosphorylation is most similar to
Oxidative phosphorylation in cellular respiration
Which process is most directly driven by light energy?
Removal of electrons from chlorophyll molecules
What is the basic role of CO2 in photosynthesis?
CO2 is fixed or incorporated into organic molecules.
True or False: The Calvin cycle has three phases: carbon fixation, reduction, and regeneration of RuBP.
