I know the equision of Meachile, but I would like to learn what is your theory to draw the graph, I mean why Glycogen is refered as [s] and V max = Product formed glycogen? An experiment was performed to determine the effects of an inhibitor on the breakdown of glycogen by an enzyme. In an accompanying experiment, the inhibitor was added to the glycogen-enzyme suspension and reacted using the same experimental conditions. The data obtained from these experiments is tabulated below.
