- Where in plant cells does the Calvin cycle take place? a. thylakoid membrane b. thylakoid space c. stroma d. granumPhotosynthesis directly opposes respiration in determining how plants influence atmospheric CO2 concentrations. When a leaf is in the light, both photosynthesis and respiration are occurring simultaneously. The data in the Table were collected from the leaf of a sagebrush plant that was enclosed in a chamber that measures the rate of CO2 exchange. The same leaf was used to collect the data in Interpret the Data in Chapter 7. Respiration is shown as a negative and photosynthesis as a positive rate of CO2 exchange. The net photosynthesis rate is the amount of CO2 (in micromoles per square meter per second) assimilated by the leaf while respiration is occurring; a positive value indicates more photosynthesis is occurring than respiration. The light exposed to the leaf is quantified as the number of photons in the 400 to 700 nm wavelength, the photosynthetic photon flux density (PPFD); 2,000 mol/m2/s is equivalent to the amount of light occurring at midday in full Sun. Observation Photosynthetic Photon Flux Density (PPFD) (mol/m2/s) Net Photosynthesis (mol/m2/s) 1 2,000 9.1 2 1,500 8.4 3 1,250 8.2 4 1,000 7.4 5 750 6.3 6 500 4.8 7 250 2.2 8 0 -2.0 Why is net photosynthesis negative when PPFD is zero? Looking at the respiration data from Interpret the Data in Chapter 7, at what temperature do you think these data were collected? Source: Data based on unpublished research by Brent Ewers, University of Wyoming.Which of the following is a correct step in the light-dependent reactions of the Z system? a. Light is absorbed at P700, and electrons flow through a pathway to NADP+, the final acceptor of the linear pathway. b. Electrons flow from photosystem II to water. c. NADP+ is oxidized to NADPH as it accepts electrons. d. Water is degraded to activate P680. e. Electrons pass through a thylakoid membrane to create energy to pump H+ through the cytochrome complex.
- Even though C4 plants require more ATP per CO₂ fixed, at higher temperatures, they are more efficient than C3 plants. Which of the following explains the effectiveness of C4 plants? contains a mutant form of Rubisco that does not bind to oxygen oxygen is prevented from entering the bundle-sheath cells where Rubisco is found Oduring the night, carbon dioxide is stored as malate so that stomata do not need to open during the day O photorespiration in C4 plants produces energy while in C3 plants, energy is consumedWhich 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.Which of the following scenarios happens during the light-dependent reaction of photosynthesis? Oxygen gas is produced in the thylakoid lumen by the oxidation of water by photosystem I. Ferrodoxin and NADP+ reductase participates in the reduction of NADP+ to NADPH. Carbon dioxide enters the plants via stomata. Rubisco attaches three molecules of ribulose bisphosphate (RuBP) to one molecule of carbon dioxide.
- 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.How do C4 plants minimize photorespiration? Multiple Choice Stomata are only opened at night, storing carbon dioxide in the stroma. During the day, the carbon dioxide is released for photosynthesis. Carbon dioxide is fixed twice in different cells. The Calvin cycle occurs in the bundle sheath cells where oxygen concentrations are lower. Carbon dioxide is fixed twice in different cells so that carbon dioxide does not come into contact with rubisco. Stomata are only opened at night, storing oxygen in malate. During the day, the oxygen is released for photosynthesis. Stomata are only opened at night, storing carbon dioxide in malate. During the day, the carbon dioxide is released for photosynthesis.If a C3 plant that normally closes its stomata during hot, dry conditions were triggered to open them instead, the most likely outcome would be that O water leaves the leaf, decreasing the rate of photosynthesis O glucose leaves the leaf, increasing the rate of photosynthesis O CO₂ enters the leaf, decreasing the rate of photosynthesis O O₂ enters the leaf, increasing the rate of photosynthesis more chlorophyll is made, increasing the rate of photosynthesis
- C4 plants have higher photosynthetic rates than C3 plants because they have an additional CO2-fixing enzyme located in the bundle sheath cells.In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d e C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight Open in ReadirIn the light dependent reactions of photosynthesis, light energy is converted into chemical energy.
