  • The main purpose for the pentose phosphate pathway are

    A. Production of pentoses for nucleic acids
    B. Producing glucose from carbon đioxie during photosynthesis
    C. Synthesis of NADPH
    D. Synthesis of amino acid intermediates
    E. All of the above

  • Well, for this question, the main purpose for the phosphogluconate pathway is to regenerate the formation of NADPH through both reaction ( oxidation/reduction) from NADP. As u can see,

    1) Answer A ( production of pentosses for nucleic acids) Well, Pentose phosphate pathway is not a production of pentosses for nucleic acids, b/c NADPH is the formation of ribose 5-phosphate from glucose 6-phosphate.

    2) Answer B ( producing glucose from CO2 during photosynthesis) there are nothing related to the main purposed of this pathwạy. but this pathway does oxidize glucose.

    3) Synthesis of NADPH ( Well, the pathway is just regenerated NADPH, not synthesis by NADPH)

    4) Synthesis of amino acid ( Yes, the pathway does produced erythrose-4-phosphate that used in the synthesis of aromatic amino acids.


    anyways, D is the correct answer....Well, Ill choose D, but maybe Ím wrong b/c Ím not good in microbiology lolz I just love to learn and know more about the function of each microorganisms, it's a very interesting class, but a lot of cephalgia Grin Grin Grin
