In an enzymatic reaction of maltase, the disaccharide maltose is hydrolyzed to glucose. In an experiment, an inhibitor X was added to the reaction. The addition of the inhibitor brought about a change in the activity of the enzyme. When the substrate concentration was 0.125 mM, the initial velocity was 0.10 mM per minute. However, Vo 7 Initial velocity changed to 0.25 mM per minute when the substrate concentration was 0.50 mM. Hence, calculate the Km of the reaction.
