  1. Please suggest a reason why you think that one is the answer

  2. Shazim ⋅

    Answer for 1 is B and 2 is D ! That was suck-eye !

    1) Is B because urea is the only chatrope and the others are detergents
    2) D because it shows relative bond specificity because it can catalyze various triglycerides with the same ester bonds.
    duhhhhhhhhhhhhhhhhhhhhhhhhhhhh 🙂

    with respect to question 2, the reason why structural or optical bond was not possible, simple because the enzyme acted on substrates that were similar in structure and contained the same type of bonds i.e relative or bond specificity
    In structural specificity the enzyme is specific not only to the type of bond but also the structure surrounding it
    Optical specificity refers to the enzyme being specific to the substrate and the optical configuration as well e.g. D and l configurations
    Hope this helped with any misinterpretations.
