Science

Which 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.
