Which enzyme reduces NADP+ to NADPH during photosynthesis?

Explanation:
In the light-dependent reactions of photosynthesis, NADP+ is reduced to NADPH by the enzyme NADP+ reductase (ferredoxin-NADP+ reductase). After light excites photosystem I, electrons are passed to ferredoxin, which then donates them to NADP+ via this enzyme. The reaction adds electrons and a proton to NADP+, forming NADPH, a reducing power needed by the Calvin cycle to convert CO2 into sugars. Rubisco is the carbon-fixing enzyme in the Calvin cycle and doesn’t reduce NADP+. ATP synthase makes ATP, not NADPH. DNA polymerase has no role in photosynthesis.
