Explain the roles of and limitations of Rubisco in photosynthesis.
Explain the roles of and limitations of Rubisco in photosynthesis. I
Explain why photosynthesis generally produces a large amount of Rubisco. Explain from the perspective of an FBI why C4 plants keep rubisco in bundle sheath cells.
Using Fick's equation for photosynthesis, explain why plants that have evolved to live in very dry areas use PEP carboxylase for the initial CO2 fixation enzyme rather than RUBISCO. Your answer should include which term Fick's equation is affected by using PEP carboxylase rather than RUBISCO
RuBisCO is an enzyme whose function can be related to the state of the stomata. When the stomata are open and photosynthesis is active, RuBisCO ribulose bisphosphate.
True/false, if false explain why Rubisco Activase can catalyze removal of a sugar from Rubisco's active site when Rubisco Activase's disulfide bridge is oxidized.
The Rubisco enzyme is regulated by numerous conditions. Do you expect Rubisco activity to increase or decrease for each of the following conditions? Explain your answer. a. When the amount of carbon dioxide in the stroma increases. b. When the amount of Mg2+in the stroma decreases. c. When the amount of H+ in the stroma decreases. d. When the amount of reduced ferredoxin in the stroma increases
1)What mechanisms have evolved to prevent Rubisco from binding O2? 2)Explain the Calvin cycvolved to prevent Rubisco from binding O2? with reference to CO2, ATP, G3P, 3PG, NADPH, RuBP, and sugar.
Porphyrin ring molecules are critical both for oxidative phosphorylation in the mitochondria and for photosynthesis in chloroplasts. Compare and contrast the role of this type of molecule in each process and explain the roles of O2 and H2O in each.
4. Photosynthesis is the pathway used to synthesize carbohydrates from: O 02. sunlight, CO2, and H20. O sunlight sunlight, CO2, and 02. CO2 5. Which of the answer choices correctly describes the role of rubisco in the Calvin cycle? None of the other answer options is correct. Rubisco uses NADPH to reduce 3-phosphoglycerate to a 3-carbon sugar Rubisco incorporates CO2 from the atmosphere into an organic molecule. Rubisco uses ATP to regenerate RuBP. 5. In the Calvin cycle, NADPH is:...
The presence of genes encoding Rubisco enzymes in the hyperthermophilic archaea Methanocaldococcus jannaschii and a species of Pyrococcus indicates that these organisms O incorporate carbon dioxide via the reverse citric acid cycle. carry out photosynthesis and incorporate carbon dioxide via the Calvin cycle. incorporate carbon dioxide via the Calvin cycle. incorporate carbon dioxide via the acetyl-CoA pathway. utilize molecular hydrogen as an electron donor in chemolithotrophic metabolism.
