Question

How does NADP+ become NADPH?

Answer 1

Conversion from NADP+ to NADPH:

1. NADP+ is the oxidized form of NADP (nicotinamide adenine dinucleotide phosphate), a coenzyme that transfers electrons in anabolic activities similar to NAD+.
2. The reduced state of NADP is NADPH. Energy from sunlight is used to extract electrons from water once a photon strikes the photosystem II (PSII) reaction center. The electrons move to photosystem I (PSI), which converts NADP+ to NADPH, via the chloroplast electron transport chain.
