Question

Read the given statements and select the correct option.
Statement 1 : Low temperature destroys enzymes by causing their denaturation.
Statement 2 : High temperature preserves the enzymes in their inactive state.
A. Both statements 1 and 2 are correct.
B. Statements 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statements 1 and 2 are incorrect.

Answer 1

Correct Answer - D
Low temperature preserves the enzymes in their inactive state. Therefore, it is used in preservation of foods inside cold storages. Low temperature present inside cold storages prevents spoilage of food.
High temperature destroys enzymes by causing their denaturation. This occurs at `50^(@)C` or so. In between the minimum and maximum temperature, the reaction velocity doubles for every `10^(@)C` rise in temperature (general rule of thumb).
