MCAT Question of the Day
    •

    Q:

    		 During the first step of glucose metabolism, an enzyme drives catalysis and binds glucose in its active site. A second site exists (away from the active site) which binds ATP (the eventual end-product of glucose metabolism). Which of the following is NOT correct in describing the mechanism behind the ATP-binding site on this enzyme?
    		 

    A

    		 The ATP-binding site is an example of feedback inhibition

    B

    		 ATP acts as a non-competitive inhibitor of the enzyme.

    C

    		 The enzyme is less active when ATP is present in high concentrations

    D

    		 The enzyme is more active when ATP is present in high concentrations
