Question

How is the enzymatic activity affected upon cooling?

Answer 1

Effect of Temperature on Enzyme Action. Temperature affects the reaction rate of enzymes, as do pH, substrate concentration and enzyme concentration. At low temperatures, enzymes have low activity. As the temperature rises the rate of reaction increases, usually 2-fold for every 10 degree Celsius rise.

Answer 2

The way the enzymatic activity affected upon cooling is as follows:

• Temperature affects the activity of enzyme which helps in chemical reactions.
• In the condition of lowering temperature, molecules and atoms become slow in motion and it reduce enzyme- substrate collisions.
• Sometimes temperature reduce its flexibility and in frozen condition some enzymes lose activity.
