The correct Answer is:
To answer the question, "NADP^(+) is reduced to NADPH in which of the following cycles?", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the reduction of NADP^(+) to NADPH. This process is crucial in various metabolic pathways, especially in plant respiration and photosynthesis. 2. **Identifying the Relevant Pathways**: The main pathways where NADP^(+) is reduced to NADPH include glycolysis, the Calvin cycle, and the hexose monophosphate pathway. We need to determine which of these pathways involves the reduction of NADP^(+). 3. **Analyzing Glycolysis**: In glycolysis, glucose is broken down into pyruvate, and during this process, NADP^(+) is indeed reduced to NADPH. Specifically, the enzyme glyceraldehyde phosphate dehydrogenase catalyzes the conversion of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate, where NADP^(+) is reduced to NADPH. 4. **Considering Other Pathways**: - **Calvin Cycle**: In the Calvin cycle, NADPH is oxidized to NADP^(+), which means this pathway does not reduce NADP^(+). - **Hexose Monophosphate Pathway**: This pathway primarily generates NADPH, but it does not involve the direct reduction of NADP^(+) as a primary step in glycolysis. 5. **Conclusion**: The correct answer to the question is that NADP^(+) is reduced to NADPH in glycolysis. Since glycolysis is also known as the Embden-Meyerhof-Parnas (EMP) pathway, both options referring to glycolysis are correct. ### Final Answer: NADP^(+) is reduced to NADPH in glycolysis (also known as the EMP pathway). ---
