Question

The temperature at which there is a maximum activity of the enzymes in humans is ${37}^{\circ }C$. The most plausible reason for this is

• A. It is the physiological temperature and is optimum for the activity of enzymes in the human body
• B. Higher temperatures can denature the proteins
• C. The activity is maximum at 37 degrees for all enzymes
• D. The optimum temperature varies for every enzyme.

Answer 1

The correct option is A

It is the physiological temperature and is optimum for the activity of enzymes in the human body

Enzymes are highly temperature sensitive, and are not functional at low temperatures and undergo denaturation at very high temperatures. Most of the enzymes in human body function optimally at the physiological temperature that is ${37}^{\circ }C$.
