What does it mean NADPH IN dark reaction
Answers
Answer:
The full form of NADPH is nicotinamide adenine dinucleotide phosphate hydrogen. It plays a crucial role in many of the chemical reactions that make up the procedure of the photosynthesis.
NADPH is a product of the first level of photosynthesis. It helps to fuel the reactions that occur in the second stage of the process of photosynthesis.
Plant cells require light energy, water, and carbon dioxide for carrying out the steps of the photosynthesis process.

Definition of NADPH (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen)
The NADPH is a cofactor and we use it for donating electrons and hydrogen to the reactions catalyzed by few enzymes.
Typically the enzymes present in the anabolic pathways that form huge molecules use NADPH (nicotinamide adenine dinucleotide phosphate hydrogen).
Whereas the enzymes that have an involvement in the breakdown of molecules use the analogue NADPH. Moreover, both plants and animals use NADPH and NADH.
On the other hand, they are typically segregated into organelles and the cytosol as well. Mitochondria uses NADH during the process of oxidative phosphorylation, whereas some enzymes in the cytosol synthesize large biomolecules using the NADPH.
The chloroplasts present in the plants also use NADPH as a part of the pathway to synthesize sugars from the sunlight and also from the carbon dioxide.
Likewise, in other reactions, NADPH carries electrons and protons into the new carbon-carbon bonds, creating sugar molecules.
It is kept at higher concentration in the cytosol than NADP+, for allowing it for the easy reduction of small molecules into the larger macromolecules.
The NADPH is more likely to lose its hydrogen and electrons when it is in higher abundance. This can be contrasted to the NADH, it is found in the lower concentration than the NAD+.
We use NADH catabolic pathways, the opposite of the anabolic pathways. This is favourable for the anabolic reaction in the cytosol.
The Functioning of The NADPH (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen)
NADPH is the typical coenzyme that we use in the reduction reactions, visible in the anabolic pathways of the organisms.
Likewise, during the formation of the sugar in the process of photosynthesis, the carbon molecules are in a chain together using the energy from the sunlight.
NADPH functions in the transferring of the electrons and displacement of hydrogen by the energy of the sunlight.
Firstly, NADPH accepts electrons and hydrogen. Simultaneously, the special enzymes transfer these particles to the NADP+ molecule.
In this reaction the NADP+ reduces when it accepts the electrons and the hydrogen, going from a positive electrical form to much negative neutral state as an NADPH molecule.
Then, the NADPH molecule oxidizes with the help of another enzyme. The NADPH works with a huge variety of enzymes. We can consider it as one of the universal electron carriers.
