The correct Answer is:
To determine where NADP⁺ is reduced to NADPH, we need to analyze the options provided: HMP (Hexose Monophosphate Pathway), Calvin Cycle, Glycolysis, and EMP (Embden-Meyerhof-Parnas pathway). ### Step-by-Step Solution: 1. **Understanding the Processes**: - **HMP (Hexose Monophosphate Pathway)**: This pathway, also known as the Pentose Phosphate Pathway, occurs in the cytosol of mammalian cells. It involves the oxidation of glucose, leading to the production of NADPH. - **Calvin Cycle**: This cycle is part of photosynthesis in C3 plants, where carbon fixation occurs, but it does not directly involve the reduction of NADP⁺ to NADPH. - **Glycolysis (EMP pathway)**: This pathway involves the breakdown of glucose into pyruvic acid and is characterized by incomplete oxidation. It does not result in the reduction of NADP⁺ to NADPH. 2. **Analyzing HMP**: - In the HMP pathway, glucose is oxidized, and during this process, NADP⁺ is indeed reduced to NADPH. This is a crucial step in the pathway as NADPH is used in various biosynthetic reactions. 3. **Conclusion**: - Based on the analysis, the correct answer is that NADP⁺ is reduced to NADPH in the **HMP (Hexose Monophosphate Pathway)**. ### Final Answer: **NADP⁺ is reduced to NADPH in the HMP (Hexose Monophosphate Pathway).** ---
