Review question its 1-12 sorry for the xtra questions in the bottom 1:2D chromatography is so named because ____ A: there are two steps: labeling with a radioactive marker and separation via chromatography B: two different solutions are used in the paper chromatography C: the molecules are separated into a linear arrangement, meaning two dimension D: two different types of radioactive markers must be used E: the process separates the molecules in two direction, first along the X and then along the Y axis 2: :Which molecule(s) regulate(s) photosynthesis by sensing the metabolic status of the chloroplast and regulating proton flow out of the thylakoid lumen?? A: ATP synthase B: antenna complex C: Chrolophyll B D: carotenoids E: chlorphyll A 3: When does A CAM plant take in atmospheric CO2? A: daytime only B: Summer day C: winter day D: nighttime only E: anytime the calvin cycle is happening 4: Where can you find ATP synthase in a plant cell ? B: in the mitochondial inner membrane C: both thylakid and inner mitochondria membrane D: only in the nucleus E: embedded in the plasma membrane 5: chloroplast kept in the daek can continue to make sugar is provided with A: NADPH, CO2, and ADP B: CO2, and ATP C: NADPH, ATP, and CO2 D: NADPH and ATP E: water and ATP 7: C3 plants are more susceptible to photorespiration than either C4 or CAM plants. Why do most plants lack the C4 pathway?? A: Switching between C3, C4, and CAM photosynthesis is very difficult for most plants B: ?Rubisco is more efficient in C3 plants when compared to rubisco of C4 and CAM plants C: Most plant species do not have vacuoles in their cells to store the malate generated from CO2 taken in during the night. D; : Photorespiration is not a serious problem for most plants.? E: There is an energetic cost to C4 and CAM pathways that only makes them advantageous in very hot and/or arid environments.? 8: In Engelmann's classic experiment, why were the oxygen-requiring bacteria clustered around the regions of Spirogyra algae that were bathed in red, blue, and violet light? A; The bacteria were immobile and that is where Engelmann happened to place them .? B; The most energy-rich wavelengths of light are found at the edges of visible and nonvisible light (ultra violet and infrared) C; Photosynthesis is most active in those wavelengths of light and thus more oxygen is consumed by the algae in those regions. D: Photosynthesis is most active in those wavelengths of light and thus more oxygen is produced by the algae in those regions.?

D: stroma 11: n order to elucidate the Calvin cycle, Calvin and his colleagues used two-dimensional paper chromatography to analyze the presence of different molecules under different conditions. What did they conclude from the accumulation of RuBP when CO2 levels were low?? A: CO2 serves as a non-competitive inhibitor of rubisco. B: RuBP is the last substrate to react in the Calvin cycle. C: RuBP only reacts with CO2 when concentrations of ATP are low D: RuBP is the first substrate to react with CO2 E: ?RuBP only reacts with CO2 in the sunlight. 12: Why isn't oxygen produced by organisms that perform anoxygenic photosynthesis? A; their membranes lack ATP synthase? B; They use a different enzyme for the initial reactions of the calvin cycle C: they use electrons donors other than water D: their photosystem do not utilize the calvin cycle E: their chorophyll contains an iron rather than magnesium A: ?there are two steps: labeling with a radioactive marker and separation via chromatography |
