Question

Based on the Lineweaver-Burke plot attached.  Kinetic data were generated in the (1) absence of any inhibitor, (2) presence of 15 µM of a reversible inhibitor, or (3) presence of 20 µM of a second (distinct) reversible inhibitor.  Purified enzyme concentration was 5 µM.  The y-intercept of Lines (A) and (B) is 0.9 sec/uM;  the y-intercept of Line (C) is 0.3 sec/uM.  The slope of Line (A) is 1.8 sec;  the slope of Lines (B) and (C) is 0.6 sec.

 

Calculate the Vmax of the reaction represented by Line (C).  Show all mathematical work, please.
