NEET Biology Photosynthesis in Higher Plants Question Bank Light Reaction Pigments

  • question_answer
    In noncyclic photophosphorylation, the pigment molecule first excited is [MHCET 2004]

    A) \[{{P}_{680}}\]

    B) \[{{P}_{700}}\]

    C) Chlorophyll-b

    D) Xanthophyll

    Correct Answer: A

    Solution :

    Green plants and algae use two types of photosystems, PS-I with chl. \[{{P}_{700}}\]in its reaction centre and PS-II with \[{{P}_{680}}\]in its reaction centre. The two photosystems are linked by a chain of electron carriers. Light excites \[{{P}_{680}}\]of PS-II to activated\[{{P}_{680}}\].
