Question

Optimum temperature for the enzyme activity for most enzymes is

• A. ${40}^o-{65}^{o}C$
• B. ${30}^o-{45}^{o}C$
• C. ${20}^o-{35}^{o}C$
• D. ${15}^o-{25}^{o}C$

Answer 1

Answer: (B)

${30}^o-{45}^{o}C$

• The temperature at which the enzyme shows its highest activity is called optimum temperature.
• Enzyme activity decreases below or above the temperature. Sometimes, it even becomes inactive. It corresponds to the body temperature of the warm-blooded animal. e.g, ${37}^o$c in humans.
  Thus, the correct answer is B.
