Question

Enzymes work at optimum temperature. Over a range $0–{40}^{\circ }C$, what would happen to the rate of enzyme controlled reactions for every ${10}^{\circ }C$ rise in temperature?

• A. The rate doubles itself
• B. Decreases by half
• C. No effect
• D. First increases than decreases

Answer 1

The correct option is A The rate doubles itself

Rate of enzymatic reaction highly depends on the temperature.
Rate of reaction doubles or decreases by half for every ${10}^{\circ }C$ change in either direction.
Rise in temperature for ${10}^{\circ }C$, doubles the rate of reaction.
So, the correct answer is 'the rate doubles itself'.
