Name the entrant and receptor molecules in TCA cycle. How many high-energy phosphates this cycle yields ?

Explanation

**Step-by-Step Solution:**

1. **Identify the Entrant Molecule:**
- The entrant molecule in the TCA (Tricarboxylic Acid) cycle is **Acetyl CoA**. This molecule is derived from the breakdown of carbohydrates, fats, and proteins, and it enters the TCA cycle after glycolysis and the link reaction.

2. **Identify the Receptor Molecule:**
- The receptor molecule in the TCA cycle is **Oxaloacetate**. This molecule combines with Acetyl CoA to form Citrate, which is the first step of the TCA cycle.
