Decreasing order organic compound in protoplasm is

Options

A. protein lipid nucleic acid vitamin
B. protein nucleic acid carbohydrate lipid
C. carbonhydrate lipid nucleic acid and vitamin
D. none of these

Answer

To answer the question regarding the decreasing order of organic compounds in protoplasm, we need to analyze the composition of protoplasm and the given options. Here’s a step-by-step breakdown:

### Step 1: Understand the Composition of Protoplasm
Protoplasm is primarily composed of water and organic compounds. The approximate composition is as follows:
- **Water**: 84%
- **Proteins**: 2%
- **Carbohydrates**: 2%
- **Nucleic Acids (RNA and DNA)**: 1.1% (0.7% RNA and 0.4% DNA)
- **Other Organic Compounds**: 0.4% (like hormones)
- **Inorganic Substances**: 1.5%

### Step 2: Identify the Organic Compounds
From the composition, the significant organic compounds present in protoplasm are:
- Proteins
- Carbohydrates
- Nucleic Acids (RNA and DNA)
- Other organic compounds (like hormones)

### Step 3: Arrange the Organic Compounds in Decreasing Order
Based on the percentages, we can arrange the organic compounds in decreasing order:
1. **Proteins** (2%)
2. **Carbohydrates** (2%)
3. **Nucleic Acids** (1.1%)
4. **Other Organic Compounds** (0.4%)

### Step 4: Analyze the Given Options
Now we will analyze the provided options:
- **Option A**: Protein, Lipid, Nucleic Acid, and Vitamin
- Incorrect because Lipids are not mentioned in the composition, and Vitamins are not present.

- **Option B**: Protein, Nucleic Acid, Carbohydrate, and Lipid
- Incorrect because the order is wrong; Carbohydrates should come before Nucleic Acids.

- **Option C**: Carbohydrate, Lipid, Nucleic Acid, and Vitamin
- Incorrect because it starts with Carbohydrates and includes Lipids and Vitamins, which are not present in significant amounts.

- **Option D**: None of these
- This is the correct option since all previous options are incorrect.

### Final Answer
The correct answer is **Option D: None of these**.
