The Lineweaver-Burk plot for an enzyme is given below in the presence and absence of its inhibitor. A 1/V (umol/min)-1 B 2 1/[S] (mmol/L)-1 a) Which line (A or B) is in the presence of inhibitor? Why? (2 points) b) The Km of the substrate = ? (2 points) c) The Vmax of the enzyme in the presence of the inhibitor = 2 (2 points)
