Enzymes are functional at ........ temperature in human body
Show Hint
Human enzymes work best at body temperature (37°C).
Updated On: Jul 18, 2026
- 17\(^\circ\)C
- 27\(^\circ\)C
- 37\(^\circ\)C
- 47\(^\circ\)C
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding enzyme activity.
Enzymes are biological catalysts that work efficiently only within a specific temperature range. Their activity depends on protein structure stability and kinetic energy of molecules.
Step 2: Human body temperature context.
The normal human body temperature is approximately 37\(^\circ\)C. At this temperature, enzymatic reactions occur at optimal speed without denaturation.
Step 3: Effect of low temperature.
At lower temperatures like 17\(^\circ\)C or 27\(^\circ\)C, enzyme activity slows down due to reduced molecular collisions. This decreases metabolic rate.
Step 4: Effect of high temperature.
At higher temperatures like 47\(^\circ\)C, enzymes may denature due to protein structure breakdown. This leads to loss of catalytic activity.
Step 5: Optimal functioning range.
37\(^\circ\)C is the ideal temperature where enzymes maintain their native structure and show maximum catalytic efficiency.
Step 6: Final conclusion.
Thus, enzymes function optimally at 37\(^\circ\)C in the human body.
