2. A certain metabolic pathway takes the following sequence. J L M N At the start of the experiment an inhibitor was added to the reactants. After the experiment it was found that there was the same concentration of J more than normal concentration of K; near absence of L, M, and N. When I was added to the inhibitor set M and N were detected. K a) At what stage of the reaction sequence did the inhibitor have its effects? b) Explain how the inhibitor affected the reaction. 1mk 1mks
