The Acetyl CoA is accepted by `"______________"` in the citric acid cycle.

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question pertains to the citric acid cycle, also known as the Krebs cycle, which is a crucial part of cellular respiration in plants and other organisms.

2. **Formation of Acetyl CoA**: Acetyl CoA is produced from pyruvic acid, which is derived from the breakdown of glucose during glycolysis. The conversion of pyruvic acid to acetyl CoA involves decarboxylation and the addition of coenzyme A.

3. **Entry into the Krebs Cycle**: Once formed, acetyl CoA enters the Krebs cycle.

4. **Reaction with Oxaloacetate**: In the Krebs cycle, acetyl CoA combines with a four-carbon compound called oxaloacetate.

5. **Formation of Citric Acid**: The reaction between acetyl CoA (which is a two-carbon molecule) and oxaloacetate (a four-carbon molecule) is catalyzed by the enzyme citrate synthase. This reaction produces citric acid, which is a six-carbon compound.

6. **Final Answer**: Therefore, the acetyl CoA is accepted by **oxaloacetate** in the citric acid cycle.
