10 Questions
What type of inhibition does sulfanilamide exhibit on the enzyme that converts PABA into folic acid?
Competitive inhibition
How does competitive inhibition affect the enzyme function compared to noncompetitive inhibition?
Can be overcome by high substrate concentrations
What is a characteristic of noncompetitive inhibitors regarding their binding sites on enzymes?
Binds to ES not free E
Which statement accurately describes uncompetitive inhibition?
Can be overcome by high substrate concentrations
How does increasing substrate concentration affect competitive inhibition?
Overcomes inhibitor binding
What distinguishes uncompetitive inhibition from competitive inhibition in terms of inhibitor binding sites?
[I] binds to ES not free E
In noncompetitive inhibition, what is a key characteristic of the inhibitor's structural resemblance with the substrate?
Inhibition cannot be overcome by addition of S
What is a distinguishing feature of competitive inhibitors in terms of their mechanism of action?
Inhibitors have structural resemblance with the substrate
How does uncompetitive inhibition differ from noncompetitive inhibition in terms of overcoming the effects of inhibitors?
Inhibition by uncompetitive inhibitors is irreversible with increased substrate levels
What action can help overcome noncompetitive inhibition?
Increasing [S] favors the inhibition by [I]
