← ScienceWhich outcome occurs when an archaeal enzyme is exposed to high temperatures?
A)Increased conformational flexibility and substrate binding
B)Active site distortion and catalysis inhibition✓
C)Higher substrate binding-site activation affinity
D)Temporary enzyme kinetic rate enhancement
💡 Explanation
A high temperature can overcome stabilizing forces, denaturing proteins. The enzyme undergoes denaturation because increased thermal energy disrupts the intramolecular bonds responsible for _conformational stability_, therefore active site shape is significantly changed, rather than allowing more accessible substrate interactions.
