Dicarboxylic acid cycle is also known as

Options

A. Calvin cycle
B. Hatch & Slack cycle
C. EMP cycle
D. TCA Cycle

Answer

**Step-by-Step Solution:**

1. **Understanding the Dicarboxylic Acid Cycle**: The dicarboxylic acid cycle is a biochemical pathway involved in the fixation of carbon dioxide in plants.

2. **Identifying the Options**: The question provides several options: Calvin cycle, Hatch and Slack cycle, EMP cycle, and TCA cycle.

3. **Analyzing Each Option**:
- **TCA Cycle**: Also known as the Krebs cycle, it occurs in the mitochondria and is involved in aerobic respiration, not photosynthesis.
- **EMP Cycle**: Stands for the Emden-Mirhoff-Parnas pathway, which is a pathway for glucose metabolism to generate ATP, not directly related to the dicarboxylic acid cycle.
- **Hatch and Slack Cycle**: This cycle occurs in C4 plants and is also known as the C4 pathway, which is different from the dicarboxylic acid cycle.
- **Calvin Cycle**: This cycle is specifically involved in the fixation of carbon dioxide to produce sugars in plants and is indeed referred to as the dicarboxylic acid cycle.

4. **Conclusion**: Based on the analysis, the dicarboxylic acid cycle is also known as the **Calvin Cycle**.

**Final Answer**: The dicarboxylic acid cycle is also known as the **Calvin Cycle**.
