How can enzymes, vitamins and hormones be classified into a single category of biological chemicals?

Options

A. help in regulating metabolism
B. are exclusively synthesized in the body of living organism as at present
C. are conjugated protiens
D. enchance oxidative metabolism

Answer

To classify enzymes, vitamins, and hormones into a single category of biological chemicals, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Functions**:
- Enzymes, vitamins, and hormones all play crucial roles in regulating various biochemical processes in the body.
- Enzymes act as catalysts to speed up chemical reactions, vitamins often serve as coenzymes or cofactors in metabolic reactions, and hormones regulate physiological processes.

2. **Synthesis in the Body**:
- Enzymes are synthesized by living organisms.
- Hormones are also synthesized in the body, specifically by endocrine glands.
- Vitamins, however, are not synthesized by the body (with some exceptions for certain vitamins like Vitamin D) and must be obtained from the diet.

3. **Classification Based on Composition**:
- Enzymes and hormones are primarily proteins or peptides.
- Vitamins are organic compounds but do not fall under the protein category. They are diverse in structure and function.

4. **Regulatory Role**:
- All three categories (enzymes, vitamins, and hormones) are involved in the regulation of metabolism.
- Enzymes catalyze reactions, vitamins assist in enzymatic functions, and hormones signal and regulate metabolic pathways.

5. **Conclusion**:
- The best classification for enzymes, vitamins, and hormones is that they all help in regulating metabolism. This is the commonality that allows them to be grouped together as biological chemicals.

### Final Answer:
Enzymes, vitamins, and hormones can be classified into a single category of biological chemicals because they all help in regulating metabolism.
