what is function of trace element which occur in protoplasm

Options

A. formation of enzymes
B. formation of hormones
C. formation of haemoglobin
D. formation of chlorophyll

Answer

### Step-by-Step Solution:

1. **Understanding Trace Elements**:
- Trace elements are minerals that are required by living organisms in very small amounts, typically less than 0.75% of their total body weight. They play crucial roles in various biological processes.

2. **Identifying Functions of Trace Elements**:
- Trace elements often act as cofactors for enzymes. Enzymes are biological catalysts that speed up chemical reactions in the body. Without these trace elements, many enzymatic reactions would not occur efficiently.

3. **Analyzing the Options**:
- **Formation of Enzymes**: Trace elements are essential for the formation and function of enzymes. This option is likely correct.
- **Formation of Hormones**: While some hormones may require minerals, trace elements are not primarily involved in hormone formation.
- **Formation of Hemoglobin**: Hemoglobin contains iron (Fe), which is not classified as a trace element since it is present in larger quantities in the body.
- **Formation of Chlorophyll**: Chlorophyll contains magnesium (Mg), which is also not a trace element as it is present in more significant amounts.

4. **Conclusion**:
- Based on the analysis, the correct function of trace elements in protoplasm is primarily related to the formation of enzymes.

### Final Answer:
The function of trace elements which occur in protoplasm is the **formation of enzymes**.
