  • Q:

    Glucose oxidase catalyses the conversion of glucose into gluconic acid with a pKa of 3.9. The buffer for glucose oxidase should be at pH 7 to maximize the activity of the enzyme. The gluconic acid produced would predominantly be in which state?

     

    A

    protonated

    B

    deprotonated

    C

    the protonated and deprotonated states would be roughly equivalent in concentration

    D

    there is no relationship between the protonation and the pH of the buffer
