Which biomolecule release maximum energy during oxidation

Options

A. lipid
B. protein
C. nucleic acid
D. carbohydrate

Answer

To determine which biomolecule releases the maximum energy during oxidation, we can analyze the four main types of biomolecules: lipids, proteins, nucleic acids, and carbohydrates.

### Step-by-Step Solution:

1. **Understanding Biomolecules**:
- The four biomolecules in question are lipids, proteins, nucleic acids, and carbohydrates. Each of these biomolecules has a different structure and energy content.

2. **Analyzing Lipids**:
- Lipids, such as fats, have a general formula of CnH2nO2. This indicates that they are in a reduced state, meaning they have less oxygen compared to carbohydrates. This reduced state allows lipids to undergo more extensive oxidation.

3. **Energy Release During Oxidation**:
- When lipids are oxidized, they release a significant amount of energy. In fact, the energy released from 1 gram of fat is approximately twice that released by carbohydrates.

4. **Comparison with Other Biomolecules**:
- Carbohydrates, while also energy-rich, do not release as much energy per gram as lipids do during oxidation.
- Proteins can also release energy, but they are primarily used for building and repairing tissues rather than as a primary energy source.
- Nucleic acids are not typically used for energy; they are involved in genetic information storage and transfer.

5. **Conclusion**:
- Based on the analysis, lipids (fats) release the maximum amount of energy during oxidation compared to carbohydrates, proteins, and nucleic acids.

### Final Answer:
- The biomolecule that releases the maximum energy during oxidation is **lipids**.
