chemical Does the distribution shown in the figure seem reasonable? . form carbon dioxide. NADPH is used to reduce carbon during the Calvin cycle. The photosynthetic pigment chlorophyll is anchored in the thylakoid membrane. NADPH A) cyanobacteria in freshwater and marine ecosystems B) grizzly bears in Alaska C) bacteria in our mouth D) fungi growing in the refrigerator E) mushrooms growing on the side of a dead tree, A) cyanobacteria in freshwater and marine ecosystems, What is the likely origin of chloroplasts? If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. b) a free, energized electron. Involves the splitting of glucose: G D) CO2isneeded tocomplete the light reactions. When the carbon dioxide concentration decreases, the Solved After reading the paragraph below, answer the | Chegg.com Biology 20 Exam 2 Review Flashcards | Quizlet B) carbon dioxide. The thylakoid membrane allows for hydrogen ions (H+) to be transported across, thus creating a charge separation. . E) of little concern, since it is part of the normal cycle for the planet. The electrons lost from the reaction center of photosystem I are replaced by electrons from A) CO2. 61) It has been argued that cutting old-growth forests and replacing them with plantations of young trees B) CO2 is needed to complete the light reactions. food . The containers are observed for a 24-hour period. grana . You are surprised to find that it is still alive when you return. A) is a nucleic acid complex. C) are located on the inner membrane of the chloroplast. In this drawing of a chloroplast, which structure represents the thylakoid membrane? C) plants produce oxygen gas by splitting CO2. Which of the following are produced during the light reactions of photosynthesis? c) they lose potential energy. A) reduced by photosynthesis, which removes carbon dioxide from the atmosphere. B) CO2 is needed to complete the light reactions. From your recent physics class you estimate that the static and kinetic coefficients of friction are 0.80.80.8 and 0.40.40.4 for the boy's shoes, and 0.50.50.5 and 0.20.20.2 for the crate. B) pigment. A) are located in the stroma. Plants appear green as they absorb these colors and reflect mostly green light. . B. Which of the following is an example of a photoautotroph? 16) Which of the following statements concerning the role of redox reactions in photosynthesis and states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization, the inheritance of one character has no effect on the inheritance of another, Is hydrolyzed to ADP, loses a third phosphate group. D) the bottom of the electron transport chain. The containers are observed for a 24-hour period. b) their electrons become excited. She placed one beaker in the shade and the other beaker beside a fluorescent lamp. Small aquatic plants are placed into three containers of water mixed with carbon dioxide. CO2 provides the carbon atoms that are incorporated into sugars in photosynthesis. through an electron transport chain molecule, Global warming due to the greenhouse effect may be. A) They help the plant conserve water and synthesize glucose efficiently under hot, dry conditions. A) carbon fixation true or false: organisms on earth are currently classified first as either plant or animal. Carbon dioxide absorption is an appropriate indicator of photosynthesis B) electromagnetism g. Scala tympani Small aquatic plants are placed into three containers of water mixed with carbon dioxide and indicator solution. A) Photosynthesis involves only reductions, while respiration involves only oxidations. B) two c) Plants usually open their stomata at night. A) The greenhouse effect is reduced by deforestation. six? b) glucose, ADP, NADP+, CO2. B) transports H+ ions from the stroma to the thylakoid space. . Carbon dioxide absorption is an appropriate indicator of photosynthesis because:_________.A) CO2 is needed to complete the light reactions.B) The energy in CO2 is used to produce ATP and NADPH.C) Plants produce oxygen gas by splitting CO2.D) CO2 is needed to produce sugars in the Calvin cycle. Kaleigh UTK Biology Chapt 7 Photosynthesis Practice Test - Quizlet The 58) Plant cells Which of the following are produced during the Calvin cycle? Which of the following statements regarding photosynthesis is false? C) is attributable to high CO2 levels. Carbon dioxide absorption is an appropriate indicator of photosynthesis B) Burning fossil fuels release carbon dioxide that was removed from the atmosphere millions of years ago. When the carbon dioxide concentration decreases, the color of the indicator solution also changes. or three? Small aquatic plants are placed into three containers of water mixed with carbon dioxide and indicator solution.
