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).** ---

    NADP is used in

    Assertion: The whole scheme of transfer of electrons, starting from the PS II uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally downhill to NADP^(+) causing it to be reduced to NADPH^(+) H^(+)~ is called the Z scheme or cyclic photophosphorylation. Reason: Both ATP and NADH + H^(+) are synthesised by this kind of electron flow.
