Excessive increase in temperature of medium causes the enzyme molecule to____________?
Correct answer: C. Denatured
- A. Activate
- B. Unaffected
- C. Denatured
- D. None of these
Explanation
Excessive heat disrupts the weak bonds that maintain an enzyme's three-dimensional shape, changing the active site and causing denaturation. A common mistake is choosing activate because moderate warming increases molecular motion, but temperatures beyond the optimum damage the enzyme.
