Correct Answer � A
Explanation

Answer- A
Red line in the graph represents a reaction with Noncompetitive inhibitor.
The above graph is called; Line weaver-Burk plot ; double reciprocal; plot.
1/v0 is plotted versus 1/S and a straight line is obtained.
This plot can be used to calculate Km and V max as well as to determine the mechanism of action of enzyme inhibitors.
In non-competitive inhibition, V max decreases (or 1/V max increases) but Km is unchanged
