15 Kinetic data for aenzyme that accepts two substrates shows typical Michaelis-Menten behavior when the concentration of one of the substrates is varied and the other held constant. However if the same experiment is repeated for different concentrations of the second substrate, then the resulting double reciprocal plots are found to be parallel to each other. What is the likely kinetic mechanism that is consistent with the other observation? (A) Random pathway (B) Ordered pathway (C) Ping-pong pathway (D) Theorell-Chance mechanism
