`"Asparticacid + A"overset("Transaminase")rarr" B + Glutamic acid"`
In the above reaction A and B respectively,

Options

A. Oxaloacetic acid , `alpha` - ketoglutaric acid
B. `alpha` - ketoglutaric acid, malic acid
C. Oxalo acetic acid , succinic acid
D. `alpha` - Ketoglutaric acid , Oxalo acetic acid

Answer

To solve the question regarding the reaction of aspartic acid with A to yield B and glutamic acid in the presence of transaminase, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction Type**:
- The reaction involves aspartic acid reacting with another compound (A) to produce glutamic acid and another compound (B). This is indicative of a transamination reaction, where an amino group is transferred from one amino acid to another.

2. **Understand the Role of Transaminase**:
- Transaminases are enzymes that facilitate the transfer of amino groups between amino acids. In this case, aspartic acid is likely donating its amino group.

3. **Identify the Compounds**:
- Aspartic acid (C4H7NO4) is known to undergo transamination with alpha-ketoglutaric acid (C5H9NO5) to produce glutamic acid (C5H9NO4) and oxaloacetic acid (C4H4O5).

4. **Determine A and B**:
- In the reaction, A must be the compound that receives the amino group from aspartic acid, which is alpha-ketoglutaric acid.
- B is the product formed from this reaction, which is oxaloacetic acid.

5. **Conclusion**:
- Therefore, A is alpha-ketoglutaric acid and B is oxaloacetic acid.

### Final Answer:
- A = Alpha-ketoglutaric acid
- B = Oxaloacetic acid
