Nobel Prize was awarded to the scientist for discovering the pathway of carbon assimilation

Options

A. Watson
B. Krebs
C. Calvin
D. Parnas.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which scientist was awarded the Nobel Prize for discovering the pathway of carbon assimilation, which is a key process in photosynthesis.

2. **Analyzing the Options**:
- **Watson**: Known for the discovery of the double helix structure of DNA, not related to carbon assimilation.
- **Krebs**: Discovered the Krebs cycle (or citric acid cycle), which is involved in cellular respiration, not directly in carbon assimilation during photosynthesis.
- **Calvin**: Malvin Ellis Calvin is recognized for his work on the Calvin cycle, which describes the pathway of carbon fixation in photosynthesis. He was awarded the Nobel Prize in 1961 for this discovery.
- **Parnas**: Known for studying carbohydrate metabolism, but not specifically for carbon assimilation in photosynthesis.

3. **Identifying the Correct Answer**: Based on the analysis, the scientist who discovered the pathway of carbon assimilation and was awarded the Nobel Prize is Malvin Ellis Calvin.

4. **Conclusion**: The correct answer to the question is **Calvin**.
