Which of the following statements is FALSE? transfer light energy to the reaction-center chlorophyll. These reactions actually have several names associated with them. oxidative phosphorylation in cellular respiration. Which of the following statements is FALSE? glycolysis can occur with or without oxygen glycolysis occurs in the mitochondria glycolysis is the first step in both aerobic and anaerobic respiration glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate. Carbon dioxide enters the plant via openings in the epidermis that are known as the stomata. To continue the cycle, RuBP (Ribulose-1, 5-bisphosphate) is prepared to accept CO 2 in the last step.. ATP (adenosine triphosphate) is consumed during Calvin cycle, because CO 2 is converted into carbohydrate, for this reaction to occur some chemical energy is necessary, so ATP gives this energy. For the following questions, compare the light reactions with the Calvin cycle of photosynthesis in plants.Use the following key: A.light reactions alone. The Calvin-Benson cycle, in which carbon is fixed, reduced, and utilized, involves the formation of intermediate sugar phosphates in a cyclic sequence. b) they are the ultimate sources of organic compounds for all nonautotrophic. Select the most accurate statement describing the basic function of the light reactions of photosynthesis. The source of the oxygen produced by photosynthesis has been identified through experiments using radioactive tracers. Which of the following statements describes why this is the case? Which of the following reactions ensures that the Calvin cycle can make a continuous supply of glucose? Carbon dioxide and oxygen enter and exit a leaf by diffusion. _____ splits water into 1/2 O2, H+, and e- . 4. Metabolic pathways are typically redox processes. A) creation of a pH gradient by pumping protons across the thylakoid membrane B) carbon fixation in the stroma C) … B) The release of oxygen does not occur at any stage of the Calvin cycle. a) the first product of carbon fixation in C4 plants is a 4-carbon compound instead of a 3-carbon compound. The light reactions of photosynthesis use chemiosmosis to produce ATP that will be used in the Calvin cycle. Which of the following does not occur during the Calvin cycle? The light reactions of photosynthesis supply the Calvin cycle with __________. Here is a look at the redox reactions that occur … Carbon from the carbon dioxide is fixed to form various intermediate molecules such as glyceraldehyde-3-phosphate. Energy in the form of ATP and NADPH then enter the Calvin cycle which occurs in the stroma of the chloroplast. In the second stage, six ATP and six NADPH are used to convert the six 3-PGA molecules into six molecules of a three-carbon sugar (G3P). The Calvin cycle uses the reduci… C4 plants differ from C3 and CAM plants in that C4 plants _____. You have planted bean seedlings (C3) and corn seedlings (C4) in soil and sealed them in an aquarium. Both minimize photorespiration but expend more ATP during carbon fixation. (Assume that the light intensity does not change.). The process was first identified by American biochemist Dr. Melvin Calvin in 1957. The reactions occur in the stroma of the chloroplasts. In C3 plants the conservation of water promotes _____. … removal of electrons from chlorophyll molecules. The Calvin cycle will generate glyceraldehyde 3-phosphate from carbon dioxide. The Calvin cycle is a process by which the carbon atoms within carbon dioxide are used to build sugars. What is the importance of the light-independent reactions in terms of carbon flow in the biosphere? Both mitochondria and chloroplasts __________. Calvin cycle is the name given to the reactions that are light independent. In plants, carbon dioxide (CO 2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells.Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis. calvin cycle krebs cycle . ultraviolet radiation and infrared radiation. In a plant cell, where are the ATP synthase complexes located? Photosynthesis stores energy in complex organic molecules, whereas respiration releases it. Select the correct molecule that is the main product of the Calvin cycle. These reactions are sometimes called the dark reactions since light is not needed if enough energy has been stored up from the previous light reactions. The light reactions of photosynthesis occur in the __________. Brainscape is a web and mobile study platform that helps you learn things faster. The rate of O2 production would decrease because the rate of ADP and NADP+ production by the Calvin cycle would decrease. The Calvin cycle has three phases: carbon fixation, reduction, and regeneration of RuBP. Even though the cycle is called the dark reaction … The Calvin cycle occurs in the thylakoid membrane of chloroplasts. The second stage of photosynthesis is the Calvin cycle; this is when the carbon is fixed to form the sugar glucose. D) regeneration of the CO2 acceptor E) consumption of ATP Which of the following processes is most directly driven by light energy? 1.transfer fixed carbon dioxide to cells in which the Calvin cycle occurs 2.open their stomata only at night 3.use PEP carboxylase to fix carbon dioxide 4.use malic acid to transfer carbon dioxide to the Calvin cycle 5.are better adapted to wet conditions Phase 1 in Calvin cycle: Carbon fixation.
