← ScienceWhich outcome occurs when high temperatures deactivate an enzyme catalyst?
A)Reaction rate decreases sharply✓
B)Equilibrium constant shifts favorably
C)Substrate specificity markedly increases
D)Enzyme production spontaneously increases
💡 Explanation
Enzyme deactivation causes reduced reaction rate because thermal denaturation increases the enzyme’s potential energy faster than increased molecular motion. Therefore activity is lost, rather than an increased specific activity within equilibrium conditions at high temperatures.
