Change in temperature from 30°C to 40°C in human body will cause:
Correct answer: C. First increase then decrease in rate of reaction
- A. Increase in rate of reaction
- B. Decrease in rate of reaction
- C. First increase then decrease in rate of reaction
- D. First increase then become constant
Explanation
The optimum temperature for the enzymes in human body is 37°C, When the temperature is increased from 30°C, the rate of reaction is also increased. At 37°C, the rate of reaction is maximum. If the temperature further increases, the rate of reaction decreases due to denaturation of enzymes at high temperature.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
