Homework Answers
Answer is B
This double-reciprocal plot helps in the distinguishing the difference between competitive and non competitive inhibition. In the competitive inhibition the rate of reaction will disturbed so the points will fall apart from straight line. But in case of non-competitive inhibition the rate of reaction will go through the straight line and all points will fall near the slope of straight line.
So the correct answer is that there is no competitive inhibitor.

Write the equations that describe the Michaelis-Menten and the Lineweaver-Burk double-reciprocal plots. Draw examples of each plot, demonstrating how Km and Vmax can be determined. On the same graphs, draw another plot where the same enzyme-catalyzed reaction is subjected to inhibition by a competitive inhibitor.
