Class 11- Biology- Chapter -11-Photosynthesis in Higher Plants Welcome to your Class 11- Biology- Chapter -11-Photosynthesis in Higher PlantsWhich 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 For the synthesis of one molecule of sucrose, how many ATP molecules are required in reduction step of the Calvin cycle? 24 ATP 12 ATP 2 ATP 18 ATP None Select the incorrect pair. 5-carbon compound--RuBP 4- cabon compound-malic acid 3-cabon compound- PGA 2-carbon compound - Aspartic acid 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 Produces carbohydrates through carbon dioxide fixation Absorbs photons into photosystem-I None Which of the following statement is/are correct for photorespiration? Coordinated of chloroplast, peroxisome and mitochondrion is essential in photorespiration 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 Glyoxylate is used in the synthesis of glycine in peroxisome None Continued evolution of 𝑂2 in suspension of an isolated chloroplast in light in the presence of ferric salt, violate dyes, etc. is called Blackmans reaction Hills reaction Emerson effect Oxygenation None Which pair is incorrect related to C4 pathway? First CO2 acceptor - PEP Location for primary (first) carboxylation - Mesophyll cells First product - PGA C4 plant - Sugarcane None The electron ejected by 𝑃680 in light reaction is initially accepted by Plastoquinone Ferredoxin ATP 𝑃 700 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. Both statement 1 and 2 are correct Both statement 1 and 2 are incorrect Statement 1 is correct but statement 2 is incorrect Statement 1 is incorrect but statement 2 is correct None Splitting of water is associated with Lumpen of thylakoid Photosystem I Both photosystem I and II Inner surface of thylakoid membrane. 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. Transpiration and water vapour Photosynthesis and oxygen Germination and carbon dioxide Respiration and carbon dioxide None Which of the following techniques has been most useful for investigating the Calvin cycle? Flash light experiment None of these X-rays technique Radioactive isotope technique 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 4 1 3 2 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 Respiration, catabolic Photosynthesis, 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:- 75% 0% 100% 25% None Which organelle out of these does not participate in photorespiration? Golgi bodies Peroxisomes Mitochondria Chloroplasts None Which is the most abundant plant pigment in the world? Chlorophyll a Chlorophyll c Chlorophyll d Chlorophyll b None Select the correct option:Dark reaction in photosynthesis is called so because it can occur in dark also it cannot occur during day light it does not directly depend on light energy it occurs more rapidly at night None The use of [ 14C] radioactive carbon by M. Calvin in algal photosynthesis studies provided All of the above That first CO2 fixation product was 3-carbon organic acid. That ATP and NADPH were used in the biosynthetic phase. That CO2 will combine with H2O to produce sugar. None Which of the following is not related with photosynthesis in purple sulphur bacteria :- Requirement of light Use of atmospheric 𝐶𝑂2 Release of oxygen Requirement of hydrogen doner None Time's upTime is Up!
