    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
