Which type of inhibitor directly competes for binding to an enzyme's active site?
competitive
noncompetitive
mixed
uncompetitive
How do the kinetics change in competitive inhibition?
Km increases
Km decreases
Vmax increases
Vmax does not change
Where is the intersection point on a Line-Weaver Burk Plot for a competitive inhibitor?
on the x-axis
on the y-axis
a point other than the x or y-axes
none (parallel lines)
What type of inhibitor binds to a site on the enzyme other than the active site and elicits a conformational change that prevents product formation?
mixed
competitive
uncompetitive
noncompetitive
How do the kinetics change in noncompetitive inhibition?
Km decreases
Km does not change
Vmax decreases
Vmax increases
Where is the intersection point on a Line-Weaver Burk Plot for a noncompetitive inhibitor?
on the x-axis
on the y-axis
a point other than the x or y-axes

What type of inhibitor binds to an enzyme at a spot other than the active site and alters both the Km and Vmax?
uncompetitive
mixed
noncompetitive
competitive
How do the kinetics change in mixed inhibition?
Km increases
Km decreases
Vmax increases
Vmax decreases
Where is the intersection point on a Line-Weaver Burk Plot for a mixed inhibitor?
on the x-axis
