← ScienceWhich outcome occurs when an enzyme nears its thermal denaturation temperature?
A)Catalytic activity diminishes significantly.✓
B)Activation energy requirements decrease notably.
C)Equilibrium shifts toward product formation.
D)Rate constants increase more slowly.
💡 Explanation
Catalytic activity diminishes greatly because the three-dimensional protein structure unfolds via protein denaturation, disrupting the active site needed for catalysis, therefore lowers reaction rate, rather than increasing enzyme efficiency.
