The correct Answer is:
**Step-by-Step Text Solution:** 1. **Identify the Context**: The question pertains to the use of radioactive carbon-14 in studying photosynthesis after World War II. 2. **Recall Historical Figures**: The key figure associated with the use of carbon-14 in photosynthesis research is Melvin Calvin, who conducted significant experiments during this period. 3. **Understand the Experiment**: Melvin Calvin used the radioactive isotope carbon-14 to trace the path of carbon in the process of photosynthesis. This allowed him to identify the sequence of reactions that occur during the conversion of carbon dioxide into organic compounds. 4. **Identify the Key Findings**: Calvin's experiments led to the discovery that the first stable product of photosynthesis is a three-carbon compound known as phosphoglyceric acid (PGA). 5. **Name the Cycle**: The pathway elucidated by Melvin Calvin is commonly referred to as the Calvin Cycle, which consists of three main phases: decarboxylation, reduction, and regeneration. 6. **Select the Correct Answer**: Based on the information, the correct answer to the question is option C, which is Melvin Calvin. **Final Answer**: C - Melvin Calvin ---

Name the scientists who first worked out the C_(4) -pathway ?

We all know that a large number of elements exist as isotopes. The isotopes of an element have same atomic number but different mass numbers. The isotopes. With higher mass number are mostly radioactive in nature. These are called radioisotopes. These isotopes have a wide range of applications. (i) Which isotope is used to study the kinetics of photosynthesis ? (ii) Name the isotope which can detect a blood clot. (iii) Which isotope is used to detect the deformity in bones, if any ?

Some experiments were carried out using Croton sp. plants to understand the process of photosynthesis. It was observed that the leaves of the plant exposed to light for longer duration accumulated more starch. However, due to presence of pre-formed starch in the leaves, it was difficult to find the net productivity on a fixed exposure to light source. Therefore, it was necessary to obtain starch free leaves in the plant before starting the experiment. After a period of illumination, the leaves were boiled in alcohol to make them colourless. Which of the following could be used to test the end product stored in the leaves?
