- Which of the following statements about the light reactions of photosynthesis are correct? 1. Absorption of light does one thing: it makes chlorophyll easier to oxidize. 2. In PSII, the rate of damage to the D1 protein can never exceeds the rate of repair. 3. Electron transport is spontaneous (exergonic) as electrons move from P680* to P700+. 4. Compared to anoxygenic photosynthesis, in oxygenic photosynthesis less light needs to be absorbed to reduce NADP+. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correctExplain the chemical pathway used to fix carbon dioxide in C3 plants in preparation for the Calvin cycle. Explain the chemical pathway used to fix carbon dioxide in C4 plants in preparation for the Calvin cycle. Explain the leaf anatomy in C3 plants and how the structure fits the function of carbon fixation. Explain the leaf anatomy in C4 plants and how the structure fits the function of carbon fixation.For which kind of plant, and in which condition, would you expect to find leaves with the highest SLA (Specific Leaf Area)? Selected Answer: a shade-Intolerant plant growing in sun Answers: a shade-tolerant plant growing in shade a shade-tolerant plant growing in sun a shade-intolerant plant growing in sun a shade-intolerant plant growing in shade
- A. The C4 plant performs photosynthesis more efficiently than the C3 when the CO2 concentration is 600ppm or less. Provide one reason why the rate of photosynthesis doesn’t change for the C4 plant when the CO2 concentration increases above 400 ppm. B. Discuss what is happening in the C3 plant when the CO2 levels are below 50 ppm. Provide one reason why this does NOT happen to the C4 plant.What are the stages of the Calvin-Benson cycle? Select all that apply. The resulting unstable six-carbon molecule splits into two three-carbon molecules of PGA. ATP and NADPH are used to convert PGA molecules to PGAL. Most of the PGAL is used to regenerate RuBP, but some is exported to the cytoplasm to produce carbohydrates. Rubisco attaches CO2 to a five-carbon organic compound called RuBP. Rubisco is used to convert PGA molecules to PGAL.Which of the following lists the stages of the Calvin cycle in order, starting with the stage where carbon dioxide is added? PGAL synthesis → carbon fixation → light reactions → regeneration of RuBP carbon fixation → PGAL synthesis → regeneration of RuBP regeneration of RuBP → carbon fixation → PGAL synthesis photorespiration → PGAL synthesis → regeneration of RuBP → carbon fixation
- Which among the following statements is INCORRECT? The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which forms a six-carbon molecule that breaks down into two 3PG molecules. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which is a reaction assisted by large quantities of RuBP carboxylase enzyme. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which decreases cell carbon dioxide levels, which increases the diffusion gradient. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which immediately becomes a six-carbon sugar that is the base for starch, sucrose, cellulose, etc.Not all plants have leaves that are green. Zebrina sp. has purple leaves. However, these plants are still photoautotrophic and so contain all of the expected components of photosynthesis. Explain how it is possible that these leaves are purple and can photosynthesize when you know that the photosynthetic pigment chlorophyll causes leaves to look green yet these are purple and not given.The Calvin cycle can be thought of as occurring in three parts or stages. Describe the stages
- For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase can be used more than once. Calvin cycle can be organized into 3 basic stages. During the stage, the enzyme catalyze the fixation of by ribulose biphosphate. For each CO2 and RuBP, two molecules of get formed. During the phase, and are used to convert 6 molecules of 3-PGA into G3P. During the phase, one molecule of G3P leaves the Calvin cycle to contribute to the formation of other compounds needed by the plant. The remaining 5 molecules of G3P regenerate . This enables the system to fix more . 3-phosphoglycerate NADPH fixation ATP pyruvate reduction…Which of the following is TRUE about CAM photosynthetic pathway? Compared to the C3 and C4 pathways, CAM photosynthesis results in greater transpiration and water loss. O By separating where carbon is initially fixed inside the leaf tissue, CAM plants can better control the gradient of carbon dioxide between the air and their leaves. CAM photosynthesis is more energy efficient than C3 photosynthesis. Compared to C3 and C4 photosynthetic pathways, the rate of CAM photosynthesis is limited.Despite CAM photosynthesis having a comparatively higher water use efficiency relative to C3 and C4 plants, its distribution is restricted primarily to desert succulents. In terms of water use efficiency, explain why CAM photosynthesis has not spread more widely.
