The initial velocity of an enzyme-catalyzed reaction is followed at various substrate concentrations. At very high substrate concentrations it is observed that the initial velocity no longer increases as more substrate is added. The velocity under these conditions is known as A) "the ultimate velocity." B) "the maximum velocity." C) "^v_[S]." D) "optimal velocity."
