The following biomolecules are arranged in increasing order of their average percentage composition of the total cellular mass . Which of these orders is correct ?

Options

A. lons `lt` Lipids `lt` Carbohydrates `lt` Nucleic acid `lt` Proteins
B. Lipids `lt` lons `lt` Carbohydrates `lt` Nucleic acids `lt` Proteins
C. lons `lt` Carbohydrates `lt` Lipids `lt` Nucleic acids `lt` Proteins
D. lons`lt` Nucleic acids `lt` Carbohydrates `lt` Lipids `lt` Proteins

Answer

To solve the question regarding the increasing order of average percentage composition of biomolecules in total cellular mass, we need to analyze the typical composition of a cell. Here’s the step-by-step breakdown:

### Step 1: Identify the Major Biomolecules in Cells
Cells are composed of various biomolecules, including:
- Water
- Proteins
- Nucleic Acids
- Carbohydrates
- Lipids
- Ions

### Step 2: Determine the Average Percentage Composition
Based on typical cellular composition, we can assign average percentage values to these biomolecules:
- Water: 70-90% (not included in the order since we focus on other biomolecules)
- Proteins: 10-15%
- Nucleic Acids: 7-8%
- Carbohydrates: ~3%
- Lipids: ~2%
- Ions: ~1%

### Step 3: Arrange the Biomolecules in Increasing Order
Now, we will arrange the biomolecules based on their average percentage composition from lowest to highest:
1. Ions (~1%)
2. Lipids (~2%)
3. Carbohydrates (~3%)
4. Nucleic Acids (~7-8%)
5. Proteins (~10-15%)

### Step 4: Write the Final Order
The correct increasing order of biomolecules based on their average percentage composition of total cellular mass is:
- Ions < Lipids < Carbohydrates < Nucleic Acids < Proteins

### Step 5: Verify the Options
Now, we would check the provided options in the question to find which one matches our derived order. Based on the analysis, option A should correctly reflect the increasing order of biomolecules.

### Final Answer
The correct increasing order of the average percentage composition of biomolecules in total cellular mass is:
**Ions < Lipids < Carbohydrates < Nucleic Acids < Proteins.**
