Class 11- Biology- Chapter -11-Photosynthesis in Higher Plants Welcome to your Class 11- Biology- Chapter -11-Photosynthesis in Higher PlantsWhich is the most abundant plant pigment in the world? Chlorophyll d Chlorophyll b Chlorophyll c Chlorophyll a None For the synthesis of one molecule of sucrose, how many ATP molecules are required in reduction step of the Calvin cycle? 24 ATP 18 ATP 12 ATP 2 ATP None Read the given statement and select the correct option. Statement 1: Carboxylation is the most crucial step of Calvin where 𝐶𝑂2 is utilised for the carboxylation of RuBP. Statement 2: Carboxylation is catalysed by the enzyme RuBisCO which results in the formation of two molecules of 3PGA. Statement 1 is incorrect but statement 2 is correct Statement 1 is correct but statement 2 is incorrect Both statement 1 and 2 are correct Both statement 1 and 2 are incorrect None Choose the correct answer from the alternatives given.Which of the following statements is not true about the noncyclic electron pathway? Absorbs photons into photosystem-II Produces NADPH Absorbs photons into photosystem-I Produces carbohydrates through carbon dioxide fixation None Which of the following is not related with photosynthesis in purple sulphur bacteria :- Use of atmospheric 𝐶𝑂2 Release of oxygen Requirement of light Requirement of hydrogen doner None During photorespiration, when two 𝑂2 molecules react with 2 moles of RUBP then how many 3−PGA molecules are formed from 2 molecules of 2 - phosphoglycolate 1 3 4 2 None Select the correct option:Dark reaction in photosynthesis is called so because it cannot occur during day light it does not directly depend on light energy it occurs more rapidly at night it can occur in dark also None The gaseous byproduct of a process in plants is essential for another vital process that releases energy. Given below are four combinations of processes and products. Choose the correct combination. Respiration and carbon dioxide Photosynthesis and oxygen Germination and carbon dioxide Transpiration and water vapour None Which organelle out of these does not participate in photorespiration? Golgi bodies Chloroplasts Mitochondria Peroxisomes None Which of the following statement is/are correct for photorespiration? Coordinated of chloroplast, peroxisome and mitochondrion is essential in photorespiration Glyoxylate is used in the synthesis of glycine in peroxisome In mitochondria when glycine is converted into serin at that time glycine first oxidized and later reduced Glycerate diffuses out of peroxisome and enters chloroplast, here it is phosphorylated None The use of [ 14C] radioactive carbon by M. Calvin in algal photosynthesis studies provided That ATP and NADPH were used in the biosynthetic phase. That first CO2 fixation product was 3-carbon organic acid. All of the above That CO2 will combine with H2O to produce sugar. None The electron ejected by 𝑃680 in light reaction is initially accepted by Ferredoxin 𝑃 700 Plastoquinone ATP None Splitting of water is associated with Both photosystem I and II Inner surface of thylakoid membrane. Lumpen of thylakoid Photosystem I None Which of the following statement is/are correct?(A) All green plants can prepare their own food.(B) Most animals are autotrophs.(C) CO2 is not required for photosynthesis.(D) Oxygen is liberated during photosynthesis.Choose the correct answer from the options given below. (B) only (A) and (B) (A) and (D) (B) and (C) None Which pair is incorrect related to C4 pathway? Location for primary (first) carboxylation - Mesophyll cells C4 plant - Sugarcane First product - PGA First CO2 acceptor - PEP None Which of the following techniques has been most useful for investigating the Calvin cycle? None of these X-rays technique Flash light experiment Radioactive isotope technique None The synthesis of complex organic substances from simple inorganic raw materials in the presence of sunlight and chlorophyll is called ..........., which is a ............ process. Respiration, anabolic Photosynthesis, catabolic Respiration, catabolic Photosynthesis, anabolic None If 8 carbon atoms have deviated from the Calvin cycle in photorespiration, then what is the total carbon loss that occurs at the end of the reaction:- 25% 75% 100% 0% None Select the incorrect pair. 3-cabon compound- PGA 4- cabon compound-malic acid 5-carbon compound--RuBP 2-carbon compound - Aspartic acid None Continued evolution of 𝑂2 in suspension of an isolated chloroplast in light in the presence of ferric salt, violate dyes, etc. is called Oxygenation Hills reaction Blackmans reaction Emerson effect None Time's upTime is Up!
