A researcher isolates an enzyme from a thermophilic bacterium and finds that its activity dramatically decreases when incubated at 25ยฐC compared to its optimal temperature of 70ยฐC. 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.

Metabolic pathways are often regulated through feedback inhibition. This means:
The substrate of a pathway stimulates the first enzyme.
Enzymes are constantly synthesized regardless of product concentration.
The end product of a pathway inhibits an earlier enzyme in the pathway.
Enzymes are degraded rapidly after catalyzing a reaction.
The term metabolism means
The sum of all the enzymatically catalysed chemical reactions constantly taking place in the cells and tissues of the living organisms
Processes that change the small molecules into larger ones
Processes that converts the large molecules into smaller ones
None of the above
