Scientist awarded Nobel Prize in 1960 for tracing the path of carbon in photosynthesis was

Options

A. Hatch
B. Huber
C. Calvin
D. Ruben

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the name of the scientist who was awarded the Nobel Prize in 1960 for tracing the path of carbon in photosynthesis.

2. **Recall Relevant Information**: The Nobel Prize in 1960 was awarded to a scientist known for his work in photosynthesis, specifically for tracing the carbon path during the process.

3. **Consider the Options**: The options provided are Hatch, Huber, Kelvin, and Rubin.

4. **Analyze Each Option**:
- **Hatch**: Known for the Hatch-Slack pathway (C4 photosynthesis), but not awarded for tracing carbon in photosynthesis.
- **Huber**: Not widely recognized for work specifically related to tracing carbon in photosynthesis.
- **Kelvin**: Melvin Calvin is known for his research on the Calvin cycle (C3 photosynthesis) and used radioactive carbon-14 to trace the path of carbon.
- **Rubin**: Not specifically known for tracing carbon in photosynthesis.

5. **Confirm the Correct Answer**: Melvin Calvin is the scientist who discovered the Calvin cycle and was awarded the Nobel Prize in 1960 for his work using radioactive carbon-14 to trace the path of carbon during photosynthesis.

6. **Final Answer**: The scientist awarded the Nobel Prize in 1960 for tracing the path of carbon in photosynthesis is Melvin Calvin.
