A researcher isolates an enzyme from a thermophilic bacterium and finds that its activity dramatically decreases when incubated at 25°C compared to its optimal temperature of 70°C. This decrease in activity is MOST likely due to:
Increased substrate affinity at lower temperatures.
Changes in the enzyme's three-dimensional structure affecting the active site.
A decrease in the activation energy of the catalyzed reaction.
An increase in the concentration of competitive inhibitors at lower temperatures.
