A high fever is dangerous to a human because

Options

A. proteins are used up qucikly
B. fats are oxidised
C. enzymes are denatured
D. BMR is Lowered

Answer

**Step-by-Step Solution:**

1. **Understanding Fever**:
- A high fever, also known as pyrexia, is defined as an increase in body temperature above the normal range. This can occur due to various reasons, including infections, tissue damage, or other unknown causes.

2. **Effects of High Fever**:
- High fever can lead to several harmful effects on the human body, such as dehydration, loss of essential salts (like sodium chloride), and can potentially cause permanent damage to vital organs such as the brain, kidneys, and liver.

3. **Identifying the Danger of High Fever**:
- Among the options provided (proteins are used up quickly, fats are oxidized, enzymes are denatured, and BMR is lowered), we need to identify which one is the primary danger associated with high fever.

4. **Understanding Enzyme Denaturation**:
- Enzymes are proteins that catalyze biochemical reactions in the body. They are sensitive to temperature changes. When the temperature rises significantly, the structure of these proteins can change, leading to denaturation.

5. **Consequences of Denaturation**:
- Denatured enzymes lose their functional shape, which is crucial for their activity. This means that the biochemical processes they facilitate can be disrupted, leading to serious metabolic issues.

6. **Conclusion**:
- Therefore, the correct answer to the question "A high fever is dangerous to a human because" is that **enzymes are denatured**.
