The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that the conversion of 1,3-bisphosphoglycerate (BPGA) to 3-phosphoglyceric acid (PGA) is an energy-yielding step. This means that during this conversion, energy is released. 2. **Analyzing the Reaction**: In this reaction, 1,3-bisphosphoglycerate (BPGA) is converted into 3-phosphoglyceric acid (PGA) with the help of the enzyme phosphoglycerate kinase and magnesium ions. 3. **Energy Release Mechanism**: The key point here is that 1,3-bisphosphoglycerate contains two phosphate groups that are linked by high-energy bonds. When these bonds are broken during the conversion to PGA, energy is released. 4. **Formation of ATP**: The energy that is released during this conversion is used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate). Thus, ATP is formed as a result of this energy release. 5. **Evaluating the Reason**: The reason states that the energy released during the conversion is trapped by the formation of ATP. This is indeed true, as ATP serves as an energy currency in the cell. 6. **Conclusion**: Both the assertion and the reason are correct statements. However, the reason provided does not fully explain why the conversion of BPGA to PGA is considered an energy-yielding step. Therefore, while both statements are true, the reason is not the correct explanation for the assertion. ### Final Answer: Both the assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
