A Lineweaver-Burk plot displays parallel lines for an enzyme in the absence and presence of increasing amounts of an inhibitor.The inhibitor in this experiment A) binds both the free enzyme and the ES complex. B) is competitive. C) alters the K_m but not the v_max. D) is uncompetitive.

Question

Quizplus · Accepted Answer
