If a protein undergoes a conformational change in an enzyme's active site, which consequence follows regarding its binding affinity?

A)Always increases for all substrates
B)Remains constant for all ligands
C)Always decreases for the substrate
D)May increase or decrease substrate

💡 Explanation

A conformational change involves spatial rearrangement because it alters the enzyme's shape and charge distribution; therefore, the binding affinity may either increase or decrease depending on how the change affects the interaction with the substrate, rather than predictably increasing or decreasing.
