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