10 Questions
Competitive inhibitors bind to the active site of the enzyme, thereby reducing the reaction velocity.
True
Non-competitive inhibitors bind to the active site of the enzyme, altering its kinetic properties.
False
Allosteric modulation occurs through the binding of molecules to the active site of the enzyme.
False
Irreversible inhibitors form a stable complex with the enzyme, resulting in complete loss of catalytic activity.
True
The optimum pH for enzymes is always pH 7.
False
Competitive inhibitors can be overcome by increasing the substrate concentration.
True
Non-competitive inhibitors are always reversible.
True
Irreversible inhibitors are always competitive inhibitors.
False
Allosteric enzymes always have a quaternary structure.
True
Aspirin is a non-competitive inhibitor of cyclo-oxygenase.
False
