Can you explain this answer? 5. is done on EduRev Study Group by NEET Students. Dark reactions do not need light. Dark reaction in photosynthesis is called so because . The dark reactions of photosynthesis (Calvin Cycle) are presented in this learning experience to show where these processes take place in the plant as well as the specific reactions involved. Instead, dark reaction uses ATP and NADPH to produce energy molecules. are solved by group of students and teacher of NEET, which is also the largest student At very low temperatures the rate of photosynthesis is slow because the enzymes are inactive. Mechanism of photosynthesis: II Dark reaction • Dark reaction process involved in photosynthesis was established by Blackman (1905). Which products formed during the light reaction of photosynthesis are used to drive the dark reaction ? B . In this reaction, carbon dioxide is converted to sugar using ATP and NADPH. Join now. (g) True Solution C.5. It is the initial stage of dark reaction, which starts when the atmospheric carbon dioxide goes into the plant cells. The association of carbon dioxide and ribulose-1, 5-bisphosphate forms a 6-carbon compound (3 … Books. Log in. Explain how during light reaction of photosynthesis, ATP synthesis is a chemiosmotic phenomenon. agree to the. 7. The equation of dark reaction may be summed up as: 6RuBP + 6CO 2 + 18ATP + 12NADPH ———→ 6RuBP + C 6 H 12 O 6 +18 ADP +18P +12 NADP. 1. It takes up O2, and uses ATP to end up with CO2. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma … The dark reaction in photosynthesis is called so because of. In photosynthesis dark reaction, is called so because- is related to Quiz on Photosynthesis. Photosynthesis takes place in two stages - the light reaction and the dark reaction. The Questions and Dark Reaction of Photosynthesis. sksrivastav280p9btzt sksrivastav280p9btzt 26.05.2018 Science Secondary School Dark reaction in photosynthesis is called because 2 What is the basis for designating C3 and C4 pathways of photosynthesis ? Answer: (b) it does not require light energy 6. Can you explain this answer? Drawings and visualizations are used to help participants conceptualize the location and steps involved in the dark reactions of photosynthesis. Dark reaction in photosynthesis is called so because. For most plants, the dark reactions take place during daytime. So, the dark reaction in photosynthesis is called so because it does not require light energy. The net reaction for photosynthesis is misleadingly simple. 7. D . Question bank for NEET. The dark reaction in photosynthesis is called so because. C . Dark reaction is the use of ATP and NADPH to drive the processes for the synthesis of food (sugars). • C3 Photosynthesis: • C3 plants Called C3 because the CO2 is first incorporated into a 3-carbon compound. By January 1, 2021 Uncategorized No Comments. As temperature increases, the rate of photosynthesis increases because the enzymes become more active. anaerobic cellular respiration. It occurs more rapidly at night. Match the following terms and definitions. Carbon Fixation. Log in. The dark reaction of photosynthesis proceeds in the stroma of the chloroplast. The unstable 6C compound then breaks down into 2 3C compounds called glycerate-3-phosphate (GP). Join now. Dark reaction in photosynthesis is called so because (A): it does not require … Jan 19,2021 - The dark reaction in photosynthesis is called so becausea)It does not depend on light energy.b)It can occur in dark also.c)It cannot occur during day light.d)It occurs more rapidly at night.Correct answer is option 'A'. During light reaction in photosynthesis, the following are formed. PEP is primary C0 2 acceptor in Join now. Dark reaction in photosynthesis is called so because Dark reaction in photosynthesis is called so because (a) It can occur in dark also (b) It does not directly depend on light energy (c) It cannot occur during day light (d) It occurs more rapidly at night Ans: (b) Dark reaction in photosynthesis is called so because it does not directly depend on light energy. the dark reaction in photosynthesis is limited by. Though it is called the "dark reaction", the Calvin cycle does not actually occur in the dark or during nighttime. 8. (b) It does not directly depend on light energy. Can you explain this answer? Can you explain this answer? (a) 8. Log in. photosynthesis in higher plants. over here on EduRev! Join now. Solution: Option (c) is the answer. Then this atmospheric CO2 is fixed via an enzyme (rubisco) that binds it to a (RuBP) ribulose-1, 5-bisphosphate (5-C compound). The light reaction takes place only in the presence of sunlight and therefore it is also called the light-dependent reaction. It depend on light energy indidectly because dark reaction depend upon atp & nadph which is produced by light reaction so i think opt a is incorrect. This reaction is called carbon fixation or the Calvin cycle. The dark reaction occurs in the stroma of the chloroplast. 1 See answer ROHan7282829 is waiting for your help. During photosynthesis oxygen in a glucose comes from (a) water (b) carbon dioxide (c) both water and carbon dioxide (d) from air So, the dark reaction in photosynthesis is called so because it does not require light energy. Rate of photosynthesis is optimum at (35-40)°C. It can occur in dark also b . Does moonlight support photosynthesis ? Therefore, it is also known as the light-independent reaction. If a plant is kept in bright light all the 24 hours for a few days, the dark reaction (biosynthetic phase) will continue to occur because the dark reaction is independent of light and it occurs simultaneously with the light dependent reaction. Physics. In photosynthesis dark reaction, is called so because- A . So the correct option is 'It occurs more rapidly at night. (d) It occurs more rapidly at night.
