The addition of these particles converts nadp+ into nadph. Nadp+ is the electron carrier that accepts the energized electrons at the end of the photosystem reactions, along with protons from the stroma to form nadph The conversion of nadp+ to nadph is primarily achieved through reduction, a process where a molecule gains electrons

This process doesn't occur spontaneously
Accepting the electrons converts nadp + to its reduced form nadph
As the name suggests, they are simply electron carriers, implying that they are going to drop these electrons at a given destination. The electrons travel through the chloroplast electron transport chain to photosystem i (psi), which reduces nadp+ to nadph The electron transport chain moves protons across the thylakoid membrane into the lumen. In this review, we describe how the two different redox coupling systems (nad + /nadh and nadp + /nadph) are deployed in plants and other organisms and discuss the importance of having both redox systems.
Nadh and nadph are very stable in basic solutions, but nad + and nadp + are degraded in basic solutions into a fluorescent product that can be used conveniently for quantitation. Once nadp+ receives two electrons and one h+ ion, it is reduced to form nadph This reduces the nadp+ molecule, and the end product, nadph, is a carrier of electrons and protons Two photosystems occur in eukaryotes and certain prokaryotes
The first is called photosystem ii (psii), which was named for its discovery order rather than for the feature order.
As indicated above, nadp + can be generated via the action of cytoplasmic and mitochondrial nad + kinases The reduction of nadp to nadph occurs in the course of various oxidation reactions The pentose phosphate pathway (ppp) is one of the most significant metabolic pathways for nadph generation.
