Protoplasmic elements form

Options

A. Proteins and enzymes
B. Nucleic acids
C. Lipids
D. All the above.

Answer

To solve the question "Protoplasmic elements form," we need to analyze the options provided and understand what protoplasm consists of.

### Step-by-Step Solution:

1. **Understanding Protoplasm**: Protoplasm is the living content of a cell, enclosed by the cell membrane. It includes the cytoplasm and the nucleus.

2. **Components of Protoplasm**: Protoplasm is made up of various elements:
- **Nucleic Acids**: These include DNA and RNA, which are essential for genetic information and protein synthesis.
- **Proteins**: These are crucial for various cellular functions and are considered the building blocks of the cell.
- **Lipids**: These are important for forming cell membranes and storing energy.
- **Carbohydrates**: These serve as energy sources and structural components.
- **Inorganic Salts and Water**: These are also part of the protoplasm, contributing to various biochemical processes.

3. **Analyzing the Options**:
- **Proteins and Enzymes**: Proteins are indeed part of protoplasm, and enzymes (which are proteins) facilitate biochemical reactions.
- **Nucleic Acids**: DNA and RNA are essential components of protoplasm.
- **Lipids**: These are also integral to the structure and function of cells.

4. **Conclusion**: Since all the options (proteins and enzymes, nucleic acids, lipids) are components of protoplasm, the correct answer is **all of the above**.

### Final Answer:
**All of the above**.
