Multiple Choice
In the presence of effector A an enzyme displays sigmoidal behavior when initial velocity is plotted against substrate concentration. With increasing concentrations of A the curve is displaced to the left (i.e., towards the ordinate) . Effector A is thus
A) a positive allosteric effector.
B) a competitive inhibitor.
C) a negative allosteric effector.
D) a non-competitive inhibitor.
E) an uncompetitive inhibitor.
