11th Class Biology Photosynthesis in Higher Plants

  • question_answer 16)
      During light reaction in photosynthesis the following are formed (a) ATP and sugar                                                             (b) hydrogen,  and sugar (c) ATP, hydrogen donor and                                (d) ATP, hydrogen and  donor


                      (c) Light dependent reaction uses solar power to generate ATP and  which provide chemical and reducing power respectively to sugar synthesising reaction of the Calvin cycle, while the  in released as a by product of light dependent reaction. Other options are incorrect because (a) ATP is produced in light reaction but sugar is produced in dark reaction. (b)  is produced by splitting of water  are released. The 2H+ is accepted by NADP to form NADPH and oxygen  is of course produced but sugar is not. (c)  donor and ATP is produced in light reaction but not the hydrogen.
