An enzyme has a km of 8uM in the absence of an inhibitor and apparent km of 12uM in the presence of the 3uM of the inhibitor calculate the ki of the inhibitor and determine the nature of the inhibitor.
why do you suppose it is that you did an oxidation-reduction titrattgn to determine its concentration instead of an acid-base titration?
