Quizplus · Accepted Answer

The fact that the full reaction is completed in tube B twice as fast as in tube A suggests that there is a decrease in the amount of active enzyme in tube A. The allosteric inhibitor likely binds to the enzyme and reduces the amount of the active form, leading to a slower reaction. Therefore, the correct answer is D, which describes a decrease in the amount of the active form of the enzyme.
