During starvation, energy is supplied by

Options

A. lysosomes
B. centrosomes
C. vacuoles
D. chromoplast

Answer

### Step-by-Step Solution

1. **Understanding Starvation**: Starvation occurs when the body does not receive food from external sources. In this state, the body needs to find alternative sources of energy to sustain its functions.

2. **Role of Lysosomes**: Lysosomes are cellular organelles that contain hydrolytic enzymes. These enzymes are responsible for breaking down various biomolecules, including carbohydrates, proteins, lipids, and nucleic acids.

3. **Autophagy Process**: During starvation, lysosomes initiate a process called autophagy. This process involves the breakdown of the cell's own components, including stored food materials, to release energy.

4. **Energy Supply**: The breakdown of stored food materials within the lysosomes provides the necessary energy for the body during starvation. This energy is crucial for maintaining cellular functions and overall metabolism.

5. **Eliminating Other Options**:
- **Centrosomes**: These are involved in cell division and do not play a role in energy supply during starvation.
- **Vacuoles**: While they are involved in storage, they do not directly supply energy during starvation.
- **Chromoplasts**: These are involved in pigmentation and do not contribute to energy supply.

6. **Conclusion**: Therefore, the correct answer to the question of which organelle supplies energy during starvation is the lysosomes.
