Which is wrong about Krebs cycle

Options

A. It occurs in mitochondira
B. It starts with 6 carbon compound
C. It is also called citric acid cycle
D. Glycolysis is linked to it through malic acid.

Answer

### Step-by-Step Solution:

1. **Identify the Options**: The question asks which statement about the Krebs cycle is incorrect. The options provided are:
- It occurs in mitochondria.
- It starts with a 6-carbon compound.
- It is also called the citric acid cycle.
- Glycolysis is linked to it through malic acid.

2. **Evaluate Each Statement**:
- **It occurs in mitochondria**: This statement is true. The Krebs cycle takes place in the mitochondrial matrix.
- **It starts with a 6-carbon compound**: This statement is also true. The cycle begins with citric acid (6-carbon compound).
- **It is also called the citric acid cycle**: This statement is true. The Krebs cycle is indeed known as the citric acid cycle.
- **Glycolysis is linked to it through malic acid**: This statement is incorrect. Glycolysis is linked to the Krebs cycle through pyruvate, not malic acid.

3. **Conclusion**: The incorrect statement regarding the Krebs cycle is that "glycolysis is linked to it through malic acid."

### Final Answer:
The wrong statement about the Krebs cycle is: **Glycolysis is linked to it through malic acid.**
