Enzymes are most functional within the temperature range of

Options

A. `15-25 ^(@)C`
B. `20-30^(@)C`
C. `30^(@)-50^(@)C`
D. `50-60^(@)C`

Answer

To determine the temperature range in which enzymes are most functional, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Enzyme Activity**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. Their activity is influenced by various factors, one of which is temperature.

2. **Temperature and Reaction Rate**: The rate of enzyme-catalyzed reactions generally increases with temperature up to a certain point. This is because higher temperatures provide more kinetic energy to the molecules involved, leading to more frequent collisions and reactions.

3. **Optimal Temperature Range**: However, enzymes have an optimal temperature range where they function most effectively. Beyond this range, the enzyme may denature (lose its functional shape), leading to a decrease in activity.

4. **Human Body Temperature**: For most enzymes in the human body, the optimal temperature range is closely related to normal human body temperature, which is approximately 37 degrees Celsius.

5. **Identifying the Range**: Based on the information, the ideal temperature range for enzyme activity is typically between 35 degrees Celsius and 40 degrees Celsius. This range allows for maximum enzyme activity without denaturation.

6. **Conclusion**: Given the options provided, the range that encompasses this optimal temperature for enzyme activity is 30 degrees Celsius to 50 degrees Celsius. Therefore, the correct answer is option C.

### Final Answer:
The enzymes are most functional within the temperature range of **30 to 50 degrees Celsius**.
