Ornithine cycle operates in

Options

A. Stomach
B. Pancreas
C. Liver
D. Oral cavity

Answer

**Step-by-Step Solution:**

1. **Understanding the Ornithine Cycle**: The ornithine cycle, also known as the urea cycle, is a biochemical pathway that converts ammonia, which is toxic, into urea, which is less toxic and can be excreted from the body.

2. **Identifying the Inputs**: The cycle takes ammonia (produced from the breakdown of amino acids) and carbon dioxide (CO2) as inputs to produce urea.

3. **Recognizing the Location of the Cycle**: The ornithine cycle occurs in a specific organ in the body. It is crucial to identify where this cycle takes place.

4. **Analyzing the Options**:
- Option A: Stomach - Not involved in the urea cycle.
- Option B: Pancreas - Not involved in the urea cycle.
- Option C: Liver - This is the organ where the ornithine cycle occurs.
- Option D: Oral cavity - Not involved in the urea cycle.

5. **Conclusion**: Based on the understanding of the ornithine cycle and the analysis of the options, the correct answer is **Option C: Liver**.
