The metabolism of a cell which decreases during prophase again starts increasing during :-

Options

A. Telophase
B. Anaphase
C. Metaphase
D. `G_(1)` -phase

Answer

To solve the question regarding the metabolism of a cell that decreases during prophase and starts increasing again during which phase, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Prophase**:
- During prophase, the cell prepares for mitosis. The chromosomes condense and become visible, the nuclear envelope breaks down, and the nucleolus disappears. This indicates a decrease in metabolic activity as the cell focuses on preparing for division.

2. **Identifying the Phases**:
- After prophase, the cell goes through several phases: metaphase, anaphase, telophase, and then cytokinesis. We need to determine which of these phases sees an increase in metabolism.

3. **Analyzing Each Phase**:
- **Metaphase**: Chromosomes are aligned at the equatorial plane. Metabolic activity is still low as the cell is focused on ensuring proper alignment of chromosomes.
- **Anaphase**: Sister chromatids are pulled apart and move towards opposite poles. Metabolism remains low as the cell is still in the process of division.
- **Telophase**: The separated chromatids reach the poles, and the nuclear envelope re-forms around each set of chromosomes. This is a crucial point where the cell begins to restore its metabolic functions as it prepares to return to interphase.
- **G1 Phase**: This is part of interphase where the cell grows and synthesizes RNA and proteins. However, this phase follows telophase and is not the immediate answer to the question.

4. **Conclusion**:
- The metabolism of the cell, which decreases during prophase, starts increasing again during **telophase**. This is because the cell is re-establishing its normal functions as it completes the division process.

### Final Answer:
The metabolism of a cell which decreases during prophase again starts increasing during **telophase**.
