Give the location of enzymes of TCA - cycle.

Explanation

### Step-by-Step Text Solution:

1. **Understanding TCA Cycle**: The TCA cycle, also known as the Tricarboxylic Acid Cycle or Citric Acid Cycle, is a crucial metabolic pathway that plays a significant role in cellular respiration. It begins with the condensation of an acetyl group with oxaloacetate to form citric acid.

2. **Enzymes Involved**: The TCA cycle involves several key enzymes that facilitate the conversion of substrates through various stages. These enzymes include:
- Citrate Synthase
- Isocitrate Dehydrogenase
- Alpha-Ketoglutarate Dehydrogenase
