Krebs cycle forms an important product

Options

A. Acetyl CoA
B. ADP
C. ATP
D. Water.

Answer

**Step-by-Step Solution:**

1. **Understanding the Krebs Cycle**: The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a crucial metabolic pathway that occurs in the mitochondria of cells. It plays a significant role in cellular respiration, where it helps in the oxidation of acetyl-CoA to produce energy.

2. **Identifying the Products**: During the Krebs cycle, several products are generated. The key products include ATP (adenosine triphosphate), NADH, FADH2, and carbon dioxide (CO2). Among these, ATP is the primary energy currency of the cell.

3. **Examining the Options**: The options provided are:
- Acetyl-CoA
- ADP
- ATP
- Water

4. **Analyzing Each Option**:
- **Acetyl-CoA**: This is not a product of the Krebs cycle; rather, it is a substrate that enters the cycle.
- **ADP**: This is not a stable product of the Krebs cycle; instead, it is converted into ATP during the cycle.
- **ATP**: This is indeed a significant product of the Krebs cycle, as it is generated through substrate-level phosphorylation.
- **Water**: While water is involved in cellular respiration, it is not a direct product of the Krebs cycle.

5. **Conclusion**: Based on the analysis, the important product formed in the Krebs cycle is ATP. Therefore, the correct answer to the question is ATP.

**Final Answer**: ATP
