Synthesis and storage of ATP molecules required for cell div. takes place in :–

Options

A. Prophase
B. `G_(1)` phase
C. Anaphase
D. `G_(2)`-phase

Answer

To determine where the synthesis and storage of ATP molecules required for cell division takes place, we can analyze the different phases of the cell cycle:

1. **Identify the phases of the cell cycle**: The cell cycle consists of several phases: G1, S, G2, and M phase. Each phase has specific functions.

2. **Examine the G1 phase**: In the G1 phase, the cell primarily focuses on growth and synthesizing proteins and RNA. ATP synthesis is not the primary function here.

3. **Examine the S phase**: During the S phase, DNA replication occurs. While energy (ATP) is required for this process, the primary focus is on DNA synthesis.

4. **Examine the G2 phase**: In the G2 phase, the cell continues to grow and prepares for mitosis. This phase is crucial for the synthesis and storage of ATP, as the cell needs energy to undergo division.

5. **Examine the M phase**: The M phase is where mitosis occurs, and while ATP is utilized during this process, it is not the phase where ATP is synthesized or stored.

6. **Conclusion**: The synthesis and storage of ATP molecules required for cell division predominantly take place in the G2 phase of the cell cycle.

**Final Answer**: The synthesis and storage of ATP molecules required for cell division takes place in the G2 phase.
