Question

A scientist is studying the enzyme X which is an important point of regulation in the metabolism of the inhabitants of Sumeru. He developed four Akademiyan-derived compounds which may possibly work against this enzyme, and tested using an eudiometer the metabolic rate of the sample cell lines. Data are below.

Time for each compound (min)
Eudiometer volume reading (mL)
  A B C D
0 83.1 62.6 89.0 66.4
5 83.2 100.6 90.2 71.4
10 83.2 83.6 95.0 77.2
15 83.2 83.6 100 84.6
20 83.3 110.8 104.6 88.2
  1. Show the properly labeled volume versus time plot for each eudiometer, with the equation of the line and R2
  2. What is the most effective inhibitor among the four compounds?
  3. It was found that the most effective inhibitor exhibits uncompetitive inhibition. Illustrate the Lineweaver-Burk plots of uninhibited and inhibited enzyme X with properly labeled axes.
