What happens to an amylase after it has been used?

After amylase has catalyzed the breakdown of starch into sugars, it remains unchanged and can be reused. Enzymes like amylase do not get consumed in the reaction; instead, they facilitate the reaction and return to their original state. This allows them to act on additional substrate molecules repeatedly. However, factors such as temperature, pH, and substrate concentration can affect the enzyme's activity over time.
