Which of the following processes is most likely to take place as a result of the influence of temperature on enzyme activity, and not because of enzyme denaturation? a. preserving food by freezing. b. increasing the cooking rate of food by using a pressure cooker. c. preventing peeled fruit from turning brown by adding ascorbic acid (an easily oxidized substance).

Option (a).

Explanation:

Enzymes are bio catalyst that can  increases the rate of biochemical reaction. Enzymes are highly pH and temperature specific. They works at optimum temperature and pH.

Excess pH and temperature can alters the enzyme structure and may result in its denaturation. Preservation of food by freezing doesnot alters the enzyme structure. Freezing only alters the enzyme activity and does not cause enzyme denaturation.

Thus, the correct answer is option (a).

the denominator has a very specific role.
