Questions and Answers

What is the thermodynamic basis for preferential ligand-binding to specific conformers?

The most stable conformation of a protein has the lowest free energy, and ligand-binding can stabilize one conformation over another.

Which of the following is a result of preferential binding of a ligand to a specific conformation?

The ligand destabilizes the protein
The ligand stabilizes one conformation over another (correct)
The protein becomes unstable
The protein becomes more flexible

How does preferential ligand-binding relate to allosteric regulation?

It can induce conformational changes that affect ligand-binding at the protein's active site, allowing for efficient and rapid regulation of protein activity in response to changes in cellular conditions.
