What is the biological significance of the temperature at which the amylase catalyzed reaction

The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.

Explanation:

Enzymes are biological catalysts that speed up the rate of chemical reactions. Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product. The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others. Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively. In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.
