Explanation:</h3>
- Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
- Enzymes work best at a specific range of temperatures known as optimum temperature.
- Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
- Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
