The mapping of the pahtway of carbon assimilation in photosythesis earned Noble Prize in 1961 to

Options

A. Melvin Calvin
B. Alfonso Corti
C. Henry Dixon
D. Carl Mobius

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who mapped the pathway of carbon assimilation in photosynthesis and received the Nobel Prize in 1961.

2. **Identifying the Scientist**: The scientist who conducted this research is Melvin Calvin. He is known for his work on the Calvin cycle, which describes how plants convert carbon dioxide into glucose during photosynthesis.

3. **Methodology Used**: Melvin Calvin used radioactive carbon isotopes (specifically Carbon-14) to trace the pathway of carbon assimilation. This method allowed him to track how carbon dioxide is fixed and transformed into organic compounds during photosynthesis.

4. **Key Findings**: Calvin's research demonstrated the process of carbon fixation, where carbon dioxide (CO2) combines with ribulose bisphosphate (RuBP) to eventually produce glucose (C6H12O6) and oxygen (O2) as a byproduct.

5. **Nobel Prize Recognition**: For his significant contributions to understanding the biochemical processes of photosynthesis, Melvin Calvin was awarded the Nobel Prize in Chemistry in 1961.

**Final Answer**: The mapping of the pathway of carbon assimilation in photosynthesis earned the Nobel Prize in 1961 to Melvin Calvin.
