- What is CAM photosynthesis and why is it better than either C3 or C4 photosynthesis in desert or very arid environments? How does it prevent water loss during the day?arrow_forwardTopic: Photosynthesis Hi. I'm having trouble determining the answer to this question. I would like to say it would be Water and NADPH. However, I am not confident. Would you help me with this question? Thank you. Original Question: The chloroplast electron transport chain requires a continuous donation of electrons from ___________ , which are used ultimately to reduce a molecule of ___________ .arrow_forwardPhotosystem II has what role in photosynthesis? Question 9 options: directly pumping protons across the chloroplast membrane synthesis of ATP from ADP and Pi release CO2 and generate NADPH fix CO2 oxidation of H2O to O2arrow_forward

H2O, CO2, and C6H12O6 C6H12O6 and O2 only CO2 and C6H12O6 only CO2 and H2O only C6H12O6, H2O, and O2arrow_forwardFor photosynthesis lab in biology 1) This lab uses spinach leaves. Name another plant that would make an interesting comparison to spinach. Explain why you think this leaf would provide an interesting comparison 2) The lights used in this experiment are 60W. What would you predict the effect of having stronger or weaker wattage bulbs would be on your results? Explain. 3)This lab uses 0.2% sodium bicarbonate. What would you predict the effect of raising or lowering the percentage would be on your results? Explain. 4)What are TWO other things that might be manipulated in an experiment using this same protocol other than the type of leaf, percent sodium bicarbonate, and wattage of light bulb? 5) What key thing do you have to look for on the graph to know for certain that your treatment has caused a significant effect?arrow_forward
- xygen Production Your experimental team has gathered data on the rate of a plant's photosynthesis, measured by oxygen production, as the light intensity was increased. The graph below was created from your gathered data. Note: Diagram 4 may also be helpful in answering the questions. Use the information in order to answer questions #28 -31. Diagram 7: Rate of Photosynthesis with increasing light intensity 200 - Pmax 150 - 100 - 50 50- -100 100 200 300 400 500 600 700 Light Intensity (arbitrary units) Glossary: 1. Pmax: The maximum pressure of oxygen gas. 2. Arbitrary units: The use of this term mean the graph is not using specific units as labels. Light intensity could be measured in lumens and oxygen production could have been measured in mm of Hg Select the best explanation for the oxgen production leveling off as the light increases in intensity. More light reduces the activity of the chlorophyll by breaking the pigment down. More light prevents water from getting to the leaf cells…arrow_forwardWhy were chloroplasts selected for the pigment extraction in the virtual lab? The researcher in the virtual lab was using waste from a fish farm to provide nutrients for the algae. What was the algae going to be used for in order to reduce CO2 levels in the city? What plant pigment is responsible for light reaction in photosynthesis?arrow_forwardWhich 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 correctarrow_forward
- 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.arrow_forwardTable 4 Gross productivity (mg/L/hr) Net productivity (mg/L/hr) Test tube % Light 2.38 1.52 100% -1.41 2 | -2.28 -3.62 - 3.89 -3.96 3 65% 25% .17 4 -0.95 -.17 10% 6. 2% LOarrow_forwardAnswer all the following questions briefly and concisely 1. Where does photosynthesis occur in a phototrophic eukaryote? 2.Why would a bacteria that uses photosynthetic processes have various colors? 3. How can fermentation be used to distinguish between different microorganism types? 4. How are routes for glucose metabolism connected to the byproducts of lipid and protein degradation? 5. Why would a living thing choose to engage in cyclic phosphorylation as opposed to noncyclic phosphorylation? 6. What role do photosynthetic pigments play in the complex that captures light? 7. Why are autotrophic organisms required to fix CO2 and also respire or ferment in addition to this?arrow_forward
