Contain membrane folds called cristae, whereas chloroplasts contain disk-like vesicles in stacks called grana. . a fuel for cellular respiration and a starting material for making other organic molecules. 30) Plant cells are protected from the harmful effects of reactive oxidative molecules by A) two Bio chapter 7, test 6.7 Flashcards | Quizlet D) chemiosmosis. . Small aquatic plants are placed into three containers of water mixed with carbon dioxide and indicator C) They allow the plant to fix carbon more efficiently in dim or cool conditions. Produces CO2: CAC b) methane. According to this figure, how do H+ ions make their way from the stroma to the thylakoid interior? E) uses noncyclic electron flow to capture energy in glucose. ignore? versa. b) orange, red, and violet. d) be inside a mitochondrion. ________ to the thylakoid compartment, generating a concentration gradient of ________. C) plants produce oxygen gas by splitting CO2. CO2 is needed to produce sugars in the Calvin cycle. C) eat other organisms that use light energy to make food molecules. Column B Plants absorb more CO2 than we thought, but D) They make it possible for the plant to use the Calvin cycle at night. Small aquatic plants are placed into three containers of water mixed with carbon dioxide and indicator solution. D) catalyze the incorporation of carbon atoms into RuBP. a) pass energy to the reaction center. C) have mitochondria but do not have chloroplasts. In the chloroplast, sugars are made in a compartment that is filled with a thick fluid called the____, Chloroplasts contain disklike membranous sacs arranged in stacks called, What is the source of energy that provides the boost for electrons during photosynthesis? Does it seem peculiar that symmetric fission is not the most probable? It is acidic, and its concentration is in continual flux as a result of its utilization by aquatic plants in photosynthesis and release in respiration of aquatic organisms. At t=120st=120 \mathrm{~s}t=120s, what is the magnitude of the acceleration a component is subjected to? . B) is best at absorbing the energy of blue-violet and red light, just like chlorophyll a. FADH2 shuttles electrons to the electron transport chain: CAC B CO2 is needed to produce sugars in the Calvin cycle. Photoautotrophs A) make sugar by using organic raw materials. 2003-2023 Chegg Inc. All rights reserved. C) The greenhouse effect will decrease the average temperature of the planet. The concentration of CO2 will decrease as plants use it in the light-dependent reactions. The movement of H+ across a membrane down its concentration gradient, Carbon dioxide absorption is an appropriate indicator of photosynthesis because. six? c) ADP ATP. d) Glucose (C6H12O6) Since the Earth's atmosphere formed, it seems to have always contained carbon dioxide in varying amounts. e) RuP. Carbon dioxide Plants get the carbon dioxide they need from the air through their leaves. 62) The greenhouse effect is A) reduced by photosynthesis, which removes carbon dioxide from the atmosphere. Energy is never created or destroyed. CO2 provides the carbon atoms that are incorporated into sugars in photosynthesis. D) the energy in CO2 is used to produce ATP and NADPH. because cellular respiration decreases when there is less ligh Carbon dioxide absorption is an appropriate indicator of photosynthesis because What type of gas would you expect to find in these bubbles? In a photosystem, clusters of chlorophyll a, chlorophyll b, and carotenoid pigments function most like, The electrons lost from the reaction center of photosystem II are replaced by electrons from. D) The greenhouse effect has no direct relationship with the Industrial Revolution of the 1800s. When the carbon dioxide concentration decreases, the color of the indicator solution also changes. C) CO 2 is needed to produce sugars in the Calvin cycle. A) cellular respiration. color of the indicator solution also changes. A) It takes several minutes for the pigment electrons to become excited. 43) Photosystem II A) They help the plant conserve water and synthesize glucose efficiently under hot, dry conditions. b) a free, energized electron. Container A is placed under normal sunlight, B under green light, and C under red light. 29) Chlorophyll b C) is a source of oxygen for cellular respiration. 3) Which of the following is an example of a photoautotroph? one? A) H and O both in glucose A) CO2. C) occurs during the light reactions. How many "turns" of the Calvin Cycle are required to produce 1 molecule of glucose? D) anaerobic metabolism. B) is analogous to the production of ATP in mitochondria. Solved After reading the paragraph below, answer the | Chegg.com Carbon dioxide initially combines with RuBP, and RuBP is regenerated to continue the Calvin cycle. Which of the following is an example of a photoautotroph? E) found throughout the plant. The Calvin cycle constructs ________, an energy-rich molecule that a plant cell can then use to make glucose or other organic molecules. 42) The electrons lost from the reaction center of photosystem II are replaced by electrons from A) one A) are located in the stroma. C) concentrated in a portion of the leaf called the stroma. D) a source of electrons for chemiosmosis. d) the Calvin cycle is triggered. B) chloroplasts; mitochondria Glycolysis is the only stage of cellular respiration that requires _______ to make ______. D. CO is needed to produce sugars in the Calvin cycle. c) a source of electrons for chemiosmosis. . E) The release of energy by the excited electron can be as heat, light, or fluorescence. 58) Plant cells D) the energy in CO2 is used to produce ATP and NADPH. B) carbon dioxide. B) grizzly bears in Alaska. Explain. . a) CO2 is needed to complete the light reactions. cellular respiration and photosynthesis pract, Biology | Unit 2 Review | Classification, Evo, 5. organisaiton: plant organisation: Transpir, Michelle Provost-Craig, Susan J.
