Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. This is because the process requires reduced NADP which is short-lived and comes from the light-dependent reactions. This decreases the rate of photosynthesis because _____. Correct answer is option 'A'. 8. answered by Lifeeasy Authors. 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. That is useless to the plant. The unstable 6C compound then breaks down into 2 3C compounds called glycerate-3-phosphate (GP). 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. The light reaction takes place only in the presence of sunlight and therefore it is also called the light-dependent reaction. Do reactions of photosynthesis called, as ‘Dark Reaction’ need light ? One iscalled the light reaction and the other one is called the darkreaction. Carbon Fixation. Dark reaction is the use of ATP and NADPH to drive the processes for the synthesis of food (sugars). Can you explain this answer? PEP is primary C0 2 acceptor in It occurs in dark. Log in. 18ATP is required for the synthesis of one molecule of glucose, 6ATP is used for the regeneration of RuBP. It takes up O2, and uses ATP to end up with CO2. You can study other questions, MCQs, videos and tests for NEET on EduRev and even discuss your questions like • … It cannot occur during day light c.

Question bank for NEET. 1 See answer ROHan7282829 is waiting for your help. Cyanobacteria and some other photosynthetic bacteria do not have chloroplasts. Q8. So the correct option is 'It occurs more rapidly at night. This is followed by a series of reactions that ultimately result in the production of CO2. Dark reactions don't require light, but they aren't inhibited by it, either. Log in. B .

Photosynthesis takes place in two stages - the light reaction and the dark reaction. Dark reaction in photosynthesis is called so because . In photosynthesis dark reaction, is called so because- A . By continuing, I agree that I am at least 13 years old and have read and Biology. During light reaction in photosynthesis, the following are formed: a. ATP and sugar. During light reaction in photosynthesis, the following are formed. community of NEET. carbon dioxide can't be absorbed. Match the following terms and definitions. It does not depend on light energy b. What is the basis for designating C3 and C4 pathways of photosynthesis ? Can you explain this answer? Which products formed during the light reaction of photosynthesis are used to drive the dark reaction ? The release of oxygen (as well as glucose synthesis) takes place during the dark reaction of photosynthesis. 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'. Chemistry. (a) 8. are solved by group of students and teacher of NEET, which is also the largest student If the answer is not available please wait for a while and a community member will probably answer this ROHan7282829 ROHan7282829 19.07.2019 Biology Secondary School In photosynthesis dark reaction, is called so because-? Apart from being the largest NEET community, EduRev has the largest solved Dark reaction in photosynthesis is called so because . (b) It does not directly depend on light energy. Dark reaction in photosynthesis is called so because a. This phase does not directly depend on the light but is dependent on the products of the light reaction. 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'.
