← ScienceWhich consequence results when disulfide bridges are cleaved in pepsin?
A)Enzyme structure becomes globally destabilized✓
B)Substrate binding affinity increases
C)Catalytic activity instantaneously increases
D)Protein aggregation dramatically is reduced
💡 Explanation
Cleaving disulfide bonds causes widespread destabilization because the covalent cross-linking from disulfide bridges maintains tertiary structure; therefore overall stability reduces rather than catalytic improvement, because the overall structural destabilization hinders specific substrate interactions.
