What is the biological significance of the temperature at which the amylase catalyzed reaction
ipn [44]

Answer:

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.
