Choose the correct statement :

Options

A. Pyruvate is formed in the mitochondrial matrix.
B. During the conversion of succinyl CoA to succinic acid a molecule of ATP is synthesized.
C. Oxygen is vital in respiration for removal of hydrogen.
D. There is complete breakdown of glucose in fermentation.

Answer

To determine the correct statement from the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Option 1**:
- The statement claims that pyruvate is formed in the mitochondrial matrix.
- However, pyruvate is actually produced during glycolysis, which occurs in the cytoplasm, not in the mitochondrial matrix.
- Therefore, **Option 1 is incorrect**.

2. **Analyze Option 2**:
- This statement suggests that during the conversion of succinyl coenzyme A to succinic acid, a molecule of ATP is synthesized.
- In reality, this conversion produces GTP (guanosine triphosphate), not ATP.
- Thus, **Option 2 is also incorrect**.

3. **Analyze Option 3**:
- This statement asserts that oxygen is vital in respiration for the removal of hydrogen.
- Oxygen acts as the terminal electron acceptor in cellular respiration, combining with hydrogen ions and electrons to form water (H2O).
- Therefore, **Option 3 is correct**.

4. **Analyze Option 4**:
- The statement claims that there is a complete breakdown of glucose in fermentation.
- This is false because fermentation is a type of anaerobic respiration that results in the partial breakdown of glucose. The complete breakdown occurs in aerobic respiration.
- Hence, **Option 4 is incorrect**.

### Conclusion:
The correct statement is **Option 3: Oxygen is vital in respiration for the removal of hydrogen**.
